Meet the Boogie Dice: an app controlled pair of dice that lets you play all kinds of games. It connects to your phone and lets you change delay, jump power, and other settings. These also have lights, so they look even cooler in the dark. Each die has a vibration motor, tilt sensor, microphone, 3 LEDs, and a rechargeable battery.
How do these self-rolling dice work? The trick is playing special tones near the dice to change colors and other settings. The Boogie Dice ship with a convenient charger.[HT]
