This is a mouse pad, USB memory, cell phone cover, or PC accessory.
This USB Finger Dance Mat is a great way to play a "Dance Dance Revolution"-style game without having to roll out the large mat and plug it into your TV. This game is powered completely by your computer's USB port, and requires no batteries or other power cables--simply plug it into a USB port and it's ready to go! A cardboard character is included; cut it out and insert your fingers into its leg slots so it can get dancin'!
