"The surface and patterns of what appears to be ordinary wallpaper are actually interfaces that act as switches or displays. The back of it is covered with a grid of sensors, conductive materials and resistors. The physical interaction allows you to dim lights, turn on home appliances, read email on the wall, or view pictures taken with a camphone.
Another version of the wallpaper acts as a barometer, changing colour according to the level of humidity detected in the atmosphere."
