oh cool. I had a professor at Hampshire College (well, I WANTED
  HIM as a professor but his classes were always full) was a
  topology nut and I'd read the amazing clippings he posted to his
  door as I could never get into his classes. [I was going to do
  quantum mechanics and wanted the topology and fractal studies.
  Just as well though - took child psychology instead and learned
  what I wanted on my own through the years without the math
  tongue emoticon ] Loved wrapping my brain around the things on
  an intuitive level. Folding in particular I find fascinating
  even more than torus stuff.
