Color Changing Wallpaper
A couple of decades ago, hypercolor shirts which changed color according to your body temperature were all the rage. That is, they were until people started getting brightly colored armpits and other embarrassing side effects. This wallpaper exploits the same theory to unveil a ‘hidden’ design as the heat is turned up. This technology has been in a bunch of different applications, but I think it still holds a lot of untapped potential in other settings (color changing frying pans, anyone?)
