Sure it’s big, but can you propose on it?

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. That is, the light panels themselves harness the energy of the sun during the day to power a colorful light show at night.

GreenPix – Zero Energy Media Wall uses thousands solar photovoltaic capture cells attached to a grid of glass panels, each of which conceals an array of computer-controlled LEDs.

The wall was constructed for visitors attending the 2008 Beijing Olympics, and located in the Xicui entertainment complex, near the site of the games.
