I had a website explaining the origin of my avatar in what I thought was helpful detail; however, I had it hosted on GeoCities, which has recently closed down.
I still have all the files from the site, so I could easily recreate it anywhere; however, since I got no comments about the site (except from one person on a different online community where I referenced the site, but forgot to provide a link... d'oh!) I don't think I'll do so. Besides, there's probably better online resources for learning about Group Theory, Algebra, and Cayley Graphs than anything I could make.
