I love the Fleet Science Museum. The spinning disk optical illusion that makes the wall move is freaky. Last Spring my GF and I spent four months building a tornado machine like the one they have. I'm working on a second one now.

There's one for your computer....they have little ones for sell at Tam.

Phys, you can use it on your class...tell them you are hypnotizing them to turn them into brilliant students who love science! The bigger a screen you can put it on the better...

I love that one...and it's easy to download. But I don't know how to download this one: http://www.johnsadowski.com/big_spanish_castle.php

And this is one of my favorites. I could probably make something in photoshop pretty similarly. You'd just take a color photo and amp up the saturation on the negative and then make a black and white copy... but I'm lazy.
