The American Mathematical Society's Mathematical Imagery includes albums of mathematically inspired works in a variety of media--computer-generated fractals, quilts, origami, sculpture, painting, and more. Each image is described and can be sent as an e-postcard. The 2013 Calendar of Mathematical Imagery features some of these beautiful works as seen on the thumbnail images below.
To order the calendar please email the AMS Public Awareness Office, with your name and mailing address. The supply is limited so please limit your order to 3 copies maximum so that others may also have the opportunity to receive a copy.
