Whenever David Bue Pedersen looks over at the pictures of his loved ones, he'll know exactly which of them are online. That's because his picture frame is no ordinary frame. Known as the "DIY instant messenger online contact signalizer picture frame thingy," he's wired it to light an LED up behind any of five pictures of friends in the frame, so he doesn't have to go back to his computer to check who's on Skype or IM — he can just glance at the frame as he walks by.

It's an awesome idea and, as the DIY in the name implies, you can make one of your own following Pedersen's instructions on his site.
