There is a LED Piano Light which is inspired by the player piano.

Designed to take advantage of the LED light's low-temperature characteristic, Piano Light's surface can be touched without causing burns.
 
Therefore this new light allows users to tickle the "ivories" of the light as if they were playing a grand concert.

Not only is it fun to play with, but it also provides sufficient illumination for reading.

Maybe this light is a playful way to provide entertaining and eco-friendly lighting in your home.
