Zoetrope
/Being a fan of animation, as well as an animator myself, I've always had a soft spot for the zoetrope. It's amazing that a simple spinning drum with slits is all you need for the illusion of life. I saw a zoetrope similar to this one by Fogtod a couple years ago at BrickCon, but it used minifigures for the animation. I have to admit I sorta prefer the low fidelity, chunky charm of this version.
