pico projector? We might just have the perfect thing. LuminAR, a project of MIT student Natan Linder, is something like a sentient desk lamp of the sort that will make any dedicated Pixar fan's heart skip a beat. It can follow a user's actions, using a camera to detect gestures and beam information down to augment whichever reality they're currently experiencing. Interestingly, the whole thing is built into a bulb socket, meaning it could be thrown into any lamp you like -- if you can do without the whole automatic motion aspect. It's based on what looks to be a Microsoft Lifecam Show webcam and what is certainly a Microvision Show WX projector, which is both focus and care free. There's a demo video after the break but, sadly, little hope that this thing will be replacing your current desktop lamp any time soon.
