If you bred a Nintendo Wii and a regular SANSA MP3 player, you'd probably end up with the Sansa SHAKER.

The SHAKER has two headphone jacks, a built in speaker and can play back MP3s for ten hours on its AAA battery. Apart from its unusual hourglass shape however, the shaker has another quirk: When you shake it, it changes songs!

The Shaker features an SD slot to store tracks and at under $100 for the 1GB version, seems to be good value.
