If you're as sick as us of doing the "I'm going this way, you go that way" shuffle whenever you run into a guy on the street, try the Indicatears—candidate for one one of the most ridiculous gadgets we've ever seen.

The lights fit behind your ears and are tied to a belt/shirt clip attachment that you can activate to signal whether you want to go left or right. I guess cyclist could use this for signaling at night, but it may be too small to be of any practical use. But at only $6.81, it may be a cheap way for mutes to avoid awkward confrontations.
