I found an optical illusion earlier today that I think may be the coolest I've ever seen. It's quite an upgrade from the old "stare at the dot on the page for 30 seconds and then look at the wall" kind. I basically understand how it works, but I wish I knew the finer details.
Here's an additional link to a thread where it's being discussed:
