A man shows off his stick-on lights, a new idea in teeth fashion.

Technology and the height of fashion don’t often go hand-in-hand. Apple devices, smartphones, and PMPs may count as a fashion accessory, but the latest processor, fastest SSD, or a next-gen graphics card don’t. That hasn’t stopped the Japanese trying to think of novel ways to make certain components fashionable, though. While the well-known bits of a PC don’t fit the bill, those little LED lights that appear on most home electronics devices apparently do. (videos)

The latest craze spreading across Japan is an LED light device that fits in your mouth. The lights can be many different colors, which you can change wirelessly on a PC, and get activated when the wearer smiles. On a dark night it can look a bit ominous as the following video demonstrates.

The device making this possible has been around for quite some time, but only now is it becoming popular. Specifically, Japanese school girls are buying them up after an advertising campaign for Japanese clothing store Laforet Harajuku used them.
