Mes-etoiles (My stars) is an interactive wall that responds to the proximity of people, and provides feedback in the form of light. This means that users are able to use their bodies to draw with the light. The wall consists of numerous squares that each holds a collection of white lights. When a person stands in front of the wall, his or her silhouette will activate the corresponding square of light. Movements will produce dynamic drawings and because of the built-in delay it's possible for one person to create rather large images.
The developers mention various uses of the wall such as users being able to express themselves, to play, to communicate or to make collective creations. The wall might also break the psychological barriers that appear between the people sharing a given space. Check out the video. There are two more videos and a lot of pictures on the wall's website.
