O.k this may be far fetched, but just imagine. When the house is at normal temprature it would be one colour. Then if the girl/boyfriend comes round for a quiet night, put the heating on and the wallpaper would change to a colour that would set the right mood.

       See the chamelon CLothing HB idea.   

       New LCD technology makes this easy but expensive... just stick sheets to the wall... (it's now as thin ac a sheet of OHP accetate and bendable)

       If you want to do this realistically, now, you'd just work with different intensities and colors of light on white or neear-white wallpaper.

       I have seen LED array projection systems that do what jutta describes (okay, I have read about them). Intended to set a mood or environment, they paint patterns and colors on a wall or projection surface.

       This exciting idea is currently being developed. Black and white electronic ink is already available and they are working on color.   

       Check out the link.
