“Rotopault” by Brad Litwin is a kinetic sculpture that “launches a ball as it rotates, then catches the ball as it swings back around, without ever missing.” Video after the break. Click here for first picture in gallery.

Incredibly simple, but for some reason incredibly hypnotic, I think because the sounds it makes as it goes through the motions are precisely rhythmic.
