"Rosetta," by Edward Alonzo (Artist, University of Vermont)1918 viewsAcrylic on Wood, 5“ x 14.5”, 2009.
Two steganographic codes, one ultilising a sculptural and one a painterly ciphertext, create a three way harmony with the encrypted data. Expressing code not solely as something visual, but also something tactile. My current avenue of investigation is Steganography and the place of Cryptography in our society. Encryption has become incredibly powerful and equally incredibly common place. The hidden nature of steganography is because either the cryptographer decides to do it, or in the more common case of "https" because the user is ignorant of its existence. The ignorance in the second case is due to the overwhelming complexity of computers and computations done by them. Which is akin to the overwhelming complexity of art and decisions made by artists. Both Computers and Art are incredibly common in our culture and yet both are incredibly overwhelming to many of the people who see them daily. Thus, stenographic painting seems the aesthetic equivalent to 'https'. To that extent, the focus has been on devising encoding systems that utilize color and orientation, and then finessing them to make them sing together.

"Embrace," by Robert Bosch (Oberlin College, Oberlin, OH)1703 views2010 Mathematical Art Exhibition, First Prize.
Stainless steel and brass, Diameter = 6 inches, thickness = 0.25 inches, 2009. 2010 Mathematical Art Exhibition, First Prize. I began by converting a drawing of a twocomponent link into a symmetric collection of points. By treating the points as the cities of a Traveling Salesman Problem and adding constraints that forced the salesman's tour to be symmetric, I constructed a symmetric simpleclosed curve that divides the plane into two pieces: inside and outside. With a water jet cutter, I cut along this Jordan curve through quarterinch thick, sixinch diameter disks of steel and brass. By swapping inside pieces I obtained two copies of the sculpture. Here, steel is inside and brass is outside. All artists are optimizers. All artists try to perform a taskcreating a piece of artworkat the highest level possible. The main difference between me and other artists is that I use optimization explicitly. Here's how I work: After I get an idea for a piece, I translate the idea into a mathematical optimization problem. I then solve the problem, render the solution, and see if I'm pleased with the result. If I am, I stop. If not, I revise the mathematical optimization problem, solve it, render its solution, and examine it. Often, I need to go through many iterations to end up with a piece that pleases me. I do this out of a love of mathematical optimizationthe theory, the algorithms, the numerous applications.  Robert Bosch (Oberlin College, Oberlin, OH) www.dominoartwork.com


"The Vase," by Harry Benke (www.harrybenke.com)1554 views2010 Mathematical Art Exhibition Second Prize.
Giclee Print. 18" x 14.8", 2009. "The Vase" is composed of a digitally modeled vase with "Lilies" which are Dini's Surfaces. A surface of constant negative curvature obtained by twisting a pseudosphere is known as Dini's Surface. Imagine cutting the pseudosphere along one of the meridians and physically twisting it. Its parametric equations are: x=acos(u)sin(v); y=asin(u)sin (v); z=a{cos(v)+ln[tan(v/2)]}+bu, where 0<= u <= 2pi and 0< v< pi. Take a=1 and b=0.2. "I'm primarily an artist. My shadow is mathematics. I'm helpless at preventing mathematics from intruding in my work and it's delightful to have the body of mathematics to work with. My art attempts to produce a nexus between mathematical beauty and the beauty of the natural world to produce a satisfying aesthetic experience."  Harry Benke (www.harrybenke.com)


"Julia's Loops," by Jennifer Ziebarth (California College of the Arts, Oakland, CA)1279 viewsDigital print, 16" x 13", 2009. This fractal image is based on a Julia set, visible in dark blue along the intersections of the loops. The loops, which all begin and end on the Julia set, also exhibit selfsimilarity, and hint at the existence of more small loops hidden behind the larger loops. "I have always been fascinated with repetition, abstraction, and the search for pattern, and this is what drew me to mathematics. As a mathematical artist, this love of repetition and detail has lead me to fractal art. As a mathematician teaching at an art college, some of my work is pedagogical in the sense of illustrating mathematical concepts in aesthetically pleasing ways; some of it is purely visual play."  Jennifer Ziebarth (California College of the Arts, Oakland, CA)


"Meditations on f(x,y)= (x^2)/2 + xy/2 – (y^4)/8," by Richard Werner (Santa Rosa Junior College, Santa Rosa, CA)1193 views2010 Mathematical Art Exhibition Third Prize.
Plastic and wood, two pieces, each 6”x7”x7”, 1998. The two pieces give alternate views of the same threedimensional surface. The sculpture has been used for classroom illustrations of the concept of partial derivatives as well as integration of functions of two variables. Since the construction is with clear plastic, a myriad of delightful views of intersecting curves can be found allowing the viewer to hypersee the surface. "I have been a recreational wood worker and sculptor for much of my life. As a mathematics teacher, I have always been captivated by the beauty of the subject and have wanted to enhance the visual concepts in whatever way I can. The two activities were destined to meet. The first mathematical art that I made was intended mainly for classroom demonstrations. The response was very positive and I began to branch out. New materials, especially metal, have captured my interest. The work that I do now is becoming a blend of my interest in math and my love of nature, with a little bit of steampunk influence creeping in as well."  Richard Werner (Santa Rosa Junior College, Santa Rosa, CA)


"Geodesic Cuboctahedron 7 frequency," by Magnus Wenninger (Saint John’s Abbey, Collegeville, MN)1160 viewsPapercraft, 12 inches in diameter, 2009. "Geodesic domes are well known as architectural structures, but generally they exhibit only triangular grids. My main interest, however, has been in having geometric patterns projected onto a spherical surface. The icosahedron is most frequently used for this purpose, but other polyhedrons can serve just as well for the same purpose. 'Geodesic Cuboctahedron 7 frequency' is the cuboctahedron in a 7 frequency basket weave pattern with 6 squares of one color and 12 rectangles of 6 other colors projected onto the surface of the cuboctahedron’s circumsphere." More information about the techniques I use to produce my artistic patterns on a spherical surface can be found in the Dover publication of my book Spherical Models (1999), originally the Cambridge University Press publication of Spherical Models (1979). Robert Webb’s Stella program is now my computer program par excellence.  Magnus Wenninger (Saint John’s Abbey, Collegeville, MN) http://www.saintjohnsabbey.org/wenninger/


"Monarch Safye," by Safieddine Bouali (University of Tunis, Tunisia)1074 viewsDigital print, 20" x 24", 2009. Deterministic 3D strange attractor built with the dynamical system:
dx/dt = 0.02 y + 0.4 x ( 0.2  y2 ) (1)
dy/dt =  x + 35 z (2)
dz/dt = 10 x  0.1 y (3)
Initial Condition (x0, y0, z0 ) = ( 0, 0.01, 0 ), fifthorder Runge Kutta method of integration, and accuracy = 105. Euclidian coordinates representation : ( y,  x, z). I have always been fascinated by the Lorenz Attractor. I like to create and simulate systems of ordinary differential equations on my computer. A simple raylight formed by a 3D model follows intricate dynamics. Visualizing an infinite trajectory drawing elegant attractors within a limited phase of space unravels the aesthetics appeal of the Deterministic Theory of Chaos. Indescriptible happiness when new strange attractors emerge in my computer screen ! These are sculptures of motion. Derived from the Sensitive Dependency on Parameters , an unique chaotic model displays an unpredictable class of attractors. Indeed, from theoretical viewpoint, no relationship between mathematical equations and attractor shapes has ever been found. Chaotic attractors are mysterious figures but reproducible in various media by everyone if mathematical formulas are clearly expressed, I think discovering unexpected strange attractors by the exploration of 3D dynamical models constitutes a full artistic principle. By unconventional ways, I search beauty.  Safieddine Bouali (University of Tunis, Tunisia) http://chaos3d.emonsite.com/


"Origami I," by Vladimir Bulatov (Artist, Corvallis, OR)1064 viewsStainless steel and bronze. Direct metal print, 4"x 4"x 4", 2008. The sculpture is inspired by 3 dimensional origami construction. 30 identical ribbons bent around the surface of a cylinder are joined together to form the shape with the rotational symmetry of an icosahedron. My artistic passions are purely mathematical images and sculptures, which express a certain vision of forms and shapes, my interpretations of distance, transformations and space. In my opinion, mathematics is not simply a profession, but rather a way of thinking, a way of life. My images and sculptures are like photographs of interesting mathematical ideas. I have always been intrigued by the possibility of showing the intrinsic richness of the mathematical world, whose charm and harmony can really be appreciated by everyone.

"A mirror pair of (3,2) torus knots embedded on tori," by sarahmarie belcastro (freelance mathematician, Hadley, MA)1056 viewsKnitted bamboo yarn (Southwest Trading Company Twize, in colors twurple and twocean (seriously)), 6.5" x 14.5" x 3", 2009.
A (p,q) torus knot traverses the meridian cycle of a torus p times and the longitudinal cycle q times. Exhibited here are the two chiral versions of the (3,2) torus knot, knitted into their embedding tori. One can represent a (p,q) torus knot on the standard flat torus by drawing a line of slope q/p. The designer of a knit torus must contend with thickening the line to make it visible (and appear continuous), compensating for the curvature of the spatially embedded torus, and discretizing the result onto the nonsquare grid formed by knit stitches.  sarahmarie belcastro (freelance mathematician, Hadley, MA) http://www.toroidalsnark.net


"Peer Below the Surface  No. 65.270," by Leo S. Bleicher (Cepheus Information Systems, San Diego, CA)1028 viewsDigital print of 3D model on photographic paper, 23” x 19”, 2009. Serial coordinate transformations interleaving symmetry preserving and symmetry breaking operations yield a stunning variety of forms. A sequence of fourteen such operations in 3D create this shape from the unit square. Small spheres are initially an array of 40000 normals to the surface at a distance of 0.05. Larger spheres represent hierarchical clustering centroids of the normals in their final positions. Sequences are selected with a genetic recombination function using esthetic appeal as the fitness function. This transformation sequence begins with a cylindrical transform around the zaxis, and finishes with a spherical coordinate transform and rotation around the yaxis. These images are from several large series exploring the creation of complex forms through sequences of simple operations or representations of simple relationships. The operations include geometric transformations, neighbor finding, attraction/repulsion and others. These computational processes attempt to replicate features of both geologic and organic morphogenesis.  Leo S.

"Three Elements 453," by Doug Dunham (University of Minnesota Duluth)1022 viewsColor print,11” by 11”, 2007. This pattern contains lizards, fish, and bats representing the three classical elements, earth, water, and air. The pattern is inspired by M.C. Escher's Notebook Drawing Number 85. In this hyperbolic pattern, four blue lizards meet headtohead, five red fish meet headtohead, and three yellow bats meet headtohead, unlike Escher's pattern in which three of each animal meet headtohead. The symmetry group of this pattern is generated by reflections across the lines of bilateral symmetry of each of the animals; its symmetry group is the hyperbolic kaleidoscope group *543, in orbifold notation. "The goal of my art is to create repeating patterns in the hyperbolic plane. These patterns are drawn in the Poincare circle model of hyperbolic geometry, which has two useful properties: (1) it shows the entire hyperbolic plane in a finite area, and (2) it is conformal, i.e. angles have their Euclidean measure, so that copies of a motif retain their same approximate shape as they get smaller toward the bounding circle. Most of the patterns I create exhibit characteristics of Escher's patterns: they tile the plane without gaps or overlaps, and if colored, they are colored symmetrically and adhere to the mapcoloring principle that adjacent copies of the motif are different colors. My patterns are rendered by a color printer. Two challenges are to design appealing motifs and to write programs that facilitate such design and replicate the complete pattern."

"Natural Cycles," by Erik Demaine (Massachusetts Institute of Technology) and Martin Demaine (Massachusetts Institute of Technology, Cambridge, MA)1002 viewsElephant hide paper, 9"x9"x9", 2009. The sculpture is a modular combination of three interacting pieces. Each piece is folded by hand from a circle of paper, using a compass to score the creases and cut out a central hole.This transformation of flat paper into swirling surfaces creates sculpture that feels alive. Paper folds itself into a natural equilibrium form depending on its creases. These equilibria are poorly understood, especially for curved creases. We are exploring what shapes are possible in this genre of selffolding origami, with applications to deployable structures, manufacturing, and selfassembly. "We explore many mediums, from sculpture to performance art, video, and magic. In our artwork we look for epiphanies, challenges, and often connections and understanding to help solve problems in mathematics."  Erik Demaine (Massachusetts Institute of Technology) http://erikdemaine.org/curved/NaturalCycles/.


"Elements," by Jeff Chyatte (Montgomery College and River Bend Studio at Water’s Edge, Washington DC)1001 viewsPainted High Carbon Steel, Impala Black Granite, Height 18” , Width 16” , Depth 16”, 2009. Fusing math, art and aesthetics, Elements incorporates mathematically significant dimensions that add an intriguing subtlety to its construction. Euclid studied the Golden Ratio 1 to 1.618 (Greek letter Phi) for its many interesting properties as described in his manuscript Elements. Those proportions were used by great artists and architects throughout the Renaissance in the form of the Golden Rectangle. The three intersecting planes that comprise Element’s core are Golden Rectangles. Their intersection creates 20 equilateral triangles, drawn from their points  an Icosahedron. Further, these rectangles use dimensions from the Fibonacci Sequence providing for a variety of mathematical implications.

"SevenColor Torus Series in BeadCrochet: Bracelet 2," by Sophie Sommer (Colgate University, Hamilton, NY; Susan Goldstine (St. Mary’s College of Maryland, St. Mary’s City); Ellie Baker (Computer scientist/Artist, Lexington, MA) 946 viewsBeadcrochet (glass beads, thread) , "11.25” x "11.25”, 20082009. One of a series of “mapcoloring” beadcrochet bracelets. The first three are examples of maps on the torus where each of seven “countries” shares a border with all six others. Such patterns prove that at least seven colors are necessary for map coloring on the torus [Heawood]. The fourth bracelet design is an embedding of the complete graph on seven vertices [K7] on the torus. The artists wish to acknowledge the extraordinary sevencolor torus designs by Norton Starr (painted hydrostone), Carolyn Yackel (crocheted yarn) and sarahmarie belcastro (knitted yarn), which inspired our development of these patterns in beadcrochet. "Beadcrochet bracelets are made by crocheting a strand of beads into a cylinder and sewing the ends together to form a torus. Visualizing finished designs from the linear strand or from 2D patterns can be quite challenging. Our design explorations started with a desire to create novel patterns that went beyond those we found in books. Noting that bracelets are topological tori, Sophie and Ellie went hunting for mathematics to inspire new patterns and found Susan’s sevencolor tori website. Susan joined the quest to design the ideal 7color torus bracelet, adding mathematical insight that gave rise to more perfect symmetry and better understanding of the relationships between designs. The four bracelets represent our collective steps in this process. As a set, they enhance our enjoyment of the beauty of the patterns, the pleasure of the craft, and the insights that come from the puzzlesolving design process."  http://faculty.smcm.edu/sgoldstine/torus7.html


"Overlapping Circles #25," by Anne Burns (Long Island University, Brookville, NY)878 viewsDigital print, 19" X 13", 2009. The subgroup of Möbius Transformations that maps the unit circle onto itself is composed with Möbius Transformations that map the unit circle into itself to produce overlapping circles. The program was written in Actionscript. I am fascinated by art, mathematics and nature and try to combine all three in my work.
