A needle felted die is pretty cool. One with QR codes is even better. But one on which each code represents a number of dice is totally neat-o-rama! Scanning a side of Shannon Henry's needle felted die pulls up Random.org's six-sided dice generator. The red pips tells you how many dice you're rolling, so you can roll up to six six-sided dice just by scanning the correct side.
