As far as MP3 players go, they don't get much smaller than the Tok Tak. It's essentially a little nub with a headphone jack, making it look like you're wearing headphones plugged into nothing. And while it might get you strange looks on the street, but you'd have empty pockets, so I guess you'd have the last laugh.

It's just a concept at the moment, but I'd wonder how well you could control a player this small. Can you even fit button on there? In any case, it's a pretty awesome design, one I'd be interested to seeing in the real world eventually. — Adam Frucci
