The D&D bracer is a fairly quick, fun, nerdy LilyPad project. The final product is a wearable bracer with a display that will randomly generate numbers between 1 and 4, 6, 8, 10, 12, 20, or 100 in response to arm movement, so it can effectively replace all of the dice in your bag for a D&D session.
