If by chance you're looking for yet another LED-heavy DIY project to tackle, you may want to take a gander at this so-called persistence-of-vision LED sphere, which will let you pump out some super-low res still images or video on a spinning 3D screen. That's accomplished using a single ring of tri-color LEDs, which spins at a rate fast enough to display any combination of red, green or blue pixels along the surface of the resulting sphere, giving you an impressive 3-bit color depth (no video of it in action though, sadly). That, of course, is slightly easier said than done, and there unfortunately isn't a step-by-step how-to to guide you through the process, though we're guessing anyone actually pondering such a project will be able to make do well enough on their own.
