Like I know you don't have anything to do... but when you've got a few minutes to waste some time check out Michael Bach's

Fun: 69 Optical Illusions & Visual Phenomena web site (http://www.michaelbach.de/ot/index.html)

These pages demonstrate visual phenomena, and optical or visual illusions that I know you'll get a kick out of.

I love optical illusions, but some of those that look like they're moving tend to make me feel pre-migraine- anybody else out there who has migraines have this same problem?
