I'm still playing around trying to learn how to accomplish tessellation patterns for the CW. I have discovered there are several free programs that allow you to create simple and sometimes complex 2d shapes that allow for tessellation.

There are also others you can purchase for a modest fee.
If you can figure the math and the concepts you can do this yourself, which is my goal. The last time I used math for math sake was 30 years ago. I pretty much have to start from scratch.
Here is a simple pattern that should be able to tessellate in a very basic fashion. By adding complexity to the surface it can add interest to the final piece. I can cut basic shapes into a 3d mesh as well as simple images so the potential for fun is on the high side.
I am calling my piece, Shattered, but I'm including the basic shape so you can build your own master piece.
