I talked, showed, listened, and looked at a lot of stuff last week at MathFest in Sacramento. Here's me with my two pieces in the MathArt at MathFest exhibition. "Three Ring Circuits" and "Octa Zigzag Primes" although my talk was about Super-Composite Numbers.

This is a surface made of supercomposite exponent worms. The phrase is self-explanatory, but if you want me to explain it, come to my talk at MAA's MathFest on Saturday August 9 in Sacramento! Free postcard for the first 200 to attend!

That’s me at the Montclair Art Walk showing Math Art to an unsuspecting audience. I even sold some pictures!

Random math art where I run! #NorCal

My first Art Fair— Montclair Art Walk in Oakland Calif. People dig the Math Art!

Math Art is all around us! (Or at least behind us)

That background picture is an octahedron in eight equal zigzaggy pieces, each one visiting all triangular lattice points near each edge of an Eulerian circuit. Whew!
