Beam, recently launched on Kickstarter, has packed a fully-featured projector into a lightbulb-sized package (maybe more of a floodlight-sized package). It's powered by any light socket and projects images up to 120 inches wide.
Beam features a 100 lumen, LED Pico projector rated for 20,000 projection hours, a 12x LED light, as well as two 2 watt speakers. It's powered by an Android computer with a 1.3 ghz dual core processor, 8 GB of storage, and has onboard Wifi and Bluetooth connections.
Beam has already met its Kickstarter goal, but you still have time to back the project and get a Beam for it's introductory price of $399. Check it out!
