LED Lights for Your Teeth
Would you like to have a dazzling smile? No problem! The latest craze spreading across Japan is an LED light device that fits in your mouth and lights up when you smile. The only problem is that you look really stupid wearing it (not a problem if you’re Japanese).
Mouth LED technology developed by Japanese artists Daito Manabe and Motoi Ishibashi were originally used to advertise a winter sale at a Japanese clothing store, Laforet Harajuku.
