The Lightmare LED watch looked pretty rad, until I tried figuring out what time was displayed on the picture. The watch lights up a single red LED on the inner ring to mark the hour, a smaller one on the outer ring to mark a five minute increment, and one to four smaller lights denoting which actual minute it is. I usually reserve counting little red dots for STDs, but now it can also be used to tell the time, and it might go well with your LED dress shirt.
