Color Changing Shower Tiles

Imagine. You walk into shower, turn the water on and the walls begin to transform themselves into psychedelic changing patterns...

"Inspired by the stunning Northern Lights of Alaska, this line features 4 × 4 glass tiles that appear black at room temperature and move through the color spectrum when temperature (warm water, radiant heat, etc) is applied. The moving color is dynamic to the temperature of the heating agent."
