While there are more than plenty media architecture projects around, most can be described as a form of spectacular self-centered architectural decoration, rather than some sort of technological answer to an existing social context within the local environment. The Moodwall [archdaily.com] might be one of the first exceptions. Moodwall is a 24-meter long interactive surface containing 25,000 LED lights, which acts as a stage for art and media in a neighborhood of Amsterdam. The wall, located in a low pedestrian tunnel, reacts to the movement of passers-by by dynamic light changes, with the overall aim to reduce the feeling of unsafeness in the local area.
The curves in the wall should make it less suitable for grafitti and improve the visibility of the content from the sides. In addition, the resolution is horizontally stretched so the images of the screen so to stimulate people to watch the imagery from outside the tunnel and prevent the tunnel to become a hang-out spot.
Reminds me of the (now defunct?) interactive waterfall.
