LED Wall.  Designed by Langarita–Navarro Arquitectos.  Located in Madrid, Spain.

This LED wall at the Medialab-Prado in central Madrid is an interactive façade made of 35, 000 LED lights that can display both still images and video.  It was commissioned by the Madrid Town Council “to develop social interaction and to offer a new digital landmark for their city which is often so closely guarded from development.”  It serves as a display for city information and “psychedelic” art.  Images below, video after the break.
