Oh, and a Lazy Susan. Designer John Edmark has created a bunch of designs for sculptures which "bloom" when spun and lit by a strobe light or are filmed with a short shutter speed.

He's also made it possible for anyone with access to a 3D printer to make their own, uploading extensive instructions onto Instructables, where he explains:
This instructable demonstrates and explains a number of different sculptures I designed that animate when they are spun and lit by a strobe light (or are captured by a video camera with a very fast shutter speed)
[They are] a solid 3D printed sculpture spinning at 550 RPMs while being videotaped at 24 frames-per-second with a very fast shutter speed (1/2000 sec). The rotation speed is carefully synchronized to the camera's frame rate so that one frame of video is captured every time the sculpture turns ~137.5º—the golden angle. Each petal on the sculpture is placed at a unique distance from the top-center of the form. If you follow what appears to be a single petal as it works its way out and down the sculpture, what you are actually seeing is all the petals on the sculpture in the order of their respective distances from the top-center.
