Optical Illusions

I've always been intrigued with Optical Illusions... the ones that were really straight lines, but look crooked. You know the type. But I've found a couple of these that are examples of Optical Illusions that *seem* to move. There is something that happens between your eyes, and your brain that 'induce' movement to compensate for the information your eye is sending your brain.

To see movement - just move your head, or look at different parts of the pictures.

Caution - some might make you a bit nauseous.

Enjoy!
