I found this neat website of optical illusions at:

The pictures that are stationary but look like they're moving are particularly fun. There are many many examples on the site, but here are two I liked:

http://www.psy.ritsumei.ac.jp/~akitaoka/rotsnake.gif
I printed them out (in black and white) and they still work...the sense of motion isn't quite as pronounced, but it's cooler in a way because you know it's not just some weird effect of staring at a computer monitor.
