A company called Crated has come up with a flexible circuit board that doubles as a shirt and controls LEDs that will sync to the music playing around you. Yes, somehow we have gone from making fun of Tron Guy to wanting to look like him in night clubs. If this sounds cool to you for a moment, please try to imagine having a conversation with someone in a club while his or her shirt puts on a Pink Floyd-esque light show to the sound of Skrillex. No telling what happens if someone "accidentally" spills a drink on the poor, debased soul wearing one of these, but hopefully it's not electrocution (or not deadly electrocution, anyway).
Philips Research has gotten in on this too, with a snazzy new fashion accessory called the Mesopic light jacket. This one makes you look like Eminem pretending to be a Christmas tree.
Spoilers for his upcoming NBC Holiday special.
