And here are some cocoa cookies:
More examples can be seen
below, along with the stl files to produce the
rollers. To make your own patterned cookies, just
print a custom roller on a nearby 3D-printer and roll the
roller over the dough before baking. More information
is given in the paper.

This is a joint project with Robert Hanson of Towson
University. For details see this draft paper:
Robert Hanson and George Hart, "Custom
3D-Printed Rollers for Frieze Pattern Cookies,"
draft paper submitted to
Bridges 2013.

The program to process an image
and create the stl files for your own rollers is
here. To run
it, you must have access to
Mathematica.
Download the stl Files
If you have access to a 3D printer, you can replicate the
rollers illustrated here from these stl files. These
were all printed in ABS plastic on my Makerbot
Replicator.
I've also included the images used as input to the
software. There files are provided for non-commercial,
