This one I just had to report on. Are you sick and tired to using a dial or button to turn up your volume? Now you don't have to with the Portable Motion Speakers from e-Revolution!

That's right, all you need to do is just move your hands upward, and sensors detect your sign language and raise the volume. You can move your hands downward to turn it down. Portable Motion Speakers can be powered by USB, AC, or 4 AA batteries. It is also compatible with all kinds of sound-makers, including MP3 players.

The Portable Motion Speakers come in black and white, for a little over $100 USD.
