Way back in 1994 I wrote an undergraduate thesis for my math degree at Reed College. It was a fun project, studying a discrete dynamic system that was an extension of the Ising model. Sort of cellular automata meets statistical mechanics. It's the only significant thing I've written that's not online (too lazy). Update July 2022: PDF is here.
A few years ago my colleagues from the Santa Fe Institute wrote a preprint from that work, Vortex Dynamics and Entropic Coulomb Forces in Ising and Potts Antiferromagnets and Ice Models. They were kind enough to list me as an author even though I barely understand half the paper! I do have the pretty pictures, though, plus a healthy appreciation of the complexity of discrete systems.
I've never met one of the co-authors, Cosma Shalizi. But thanks to his having a weblog I now know more about him than the other guys.
