This huge LED screen displays mesmerizing patterns of light and video to passersby. But the really amazing thing about the enormous wall of light is that it’s completely self-sustaining.

Remember the oh-so-cool RGBy Desk I showed you a few weeks back? The desk uses color sensors and tons of RGB LEDs to change colors to match items placed on top of it. But it was a one-of-a-kind piece that would probably cost thousands of dollars even if you could buy one.

The RGBy desk uses small clusters of photo sensors and multicolored LEDs to work its color-changing magic.
