That's amazing. It just goes on and on with beautiful plots. About halfway down, there's a section on understanding the Riemann sphere:

> From what I can tell, one of the settings used to deal with division by 0 is the so-called Riemann sphere, which is where we take a space shuttle and use it to fly over and drop a cow on top of a biodome, and then have the cow indiscriminately fire laser beams at the grass inside and around the biodome. That's my intuitive understanding of it anyway.

And there's even animation (with Mathematica source) for this one. However:

(I am not a mathematician) but if you want an actual explanation of the Riemann sphere, I really like the one given in "Visual Complex Analysis" by Tristan Needham. It's really very cool. Google books may have it.

This site is amazing though. It just keeps going...
