A nifty little idea turns flashing LEDs into a pseudo TV. Running off a timer, FakeTV's lights flit in patterns that reflect different types of shows—less motion for a news program, more for a drama. Even the colors change to reflect what might be on the screen, with a blue glow for water scenes to a reddish cast for game shows.

The device saves money from just running today's power-hungry TVs. Granted, it can take many months to recoup the $40 price tag. But don't forget the wear and tear saved on your $2,000 plasma.
