As an electronics engineer and dabbler in recreational mathematics, I have discovered artistic forms in the mathematical and engineering graphs and diagrams that I used. I hung copies of them on my office wall to share with my coworkers. Now retired after 43 years (and as many patents), I am making them available on Zazzle.

Each design has an interesting story that is summarized in its Long Description. You may impress your friends by explaining the design. For designs that are connected to a patent, I give the patent number for those who would like to learn more. (Search the United States Patent and Trademark Office web site http://www.uspto.gov/ if you like.)

These designs make great gifts for college students studying math, science, or engineering. Or for professionals working in any of those fields.
