optical toys/ Illusions

Alright...so i was looking at some optical toys on a site. I like most of the devices but there is one that is my favorite and that would be the Zoetrope. The Zoetrope was invented in 1834 by a man named: William Horner. To create the motion the "drum" is spun, the faster you rotate it the "smoother" it moves to create the illusion. so if you want to check it out just look under: links and experience the optical toys/ illusions.
