John Edmark has created a fascinating series of fibonacci zoetrope sculptures that feel like magic. Watch them in action. It's hypnotizing.
The recursive nature of the sequence used to build them and the filming technique—with the camera "set to a very short shutter speed (1/4000 sec) in order to freeze the spinning sculpture" but with natural light—make them look as if the sculptures were growing forever.
You can see Edmark makes them here.
Here's another video filmed under a strobe light:
