Henry Segerman
I am currently a post-doctoral lecturer at the University of Texas at Austin. I teach classes, and do research in 3-dimensional geometry and topology, particularly involving ideal triangulations.
I am interested in mathematical and typographical art of various kinds, and am active in the online 3-dimensional virtual world Second Life, mostly for the artistic possibilities. I also juggle and (occasionally) play Go.

It was discovered by A. J. W. Duijvestijn in 1978.
The CSS for the rollover effect was derived from an example by Tanked Up Underwater Imaging. They used an idea by Tanfa.
