Japanese designers Motoi Ishibashi and Daito Manabe have created “LED smiles.” The pair was inspired by "LED throwies," or bundles of LED lights attached to a magnet.
It’s said that the light-up mouths were originally featured in a fashion advertisement in a winter sale at a Japanese clothing store, and now they're starting to take off as an accessory.
The LED smiles can easily be affixed to your teeth and glow different colors while you smile. Besides, the colors can be changed wirelessly through a computer interface.
