Orb is a sublime 3D spinning device that can display smooth video or static images. The device uses a spinning ring with tri-color LEDs inside, and relies on precise angular sensing and persistence-of-vision to create the effect of a spherical display surface. The Orb is hundreds of computer-controlled LEDs soldered into a ring that spins at an impressive 1,600 rpm. A computer synchronizes the LEDs to project animated digital images in full 3-D.
You'll find documentation of the complete project and more videos, here.
