So the sound quality will probably be less than mind blowing, but this is still a cool speaker concept.

Stick one of these 4-inch soundpads onto any surface, and you create a speaker.

The acoustics will vary depending on that you stick the speaker to, and they're not wireless so you're still going to get unsightly cords, but still, for $17.99 for a pair, they're sure to get your mates talking.
