File this under "Awesomeness". Some dude actually took the time to "port" DDR to BASIC for the TI-83/TI-84 calculators. Unlike the original DDR where you must use your feet to dance like a complete jackass, this one lets you use your fingers. By using the directional pad on the calculator, you have to "type" with the beat. While I'm sure this will bring joy to all high school students bored in math class, I'm skeptical as to how fast this runs on a TI-83 or TI-84.
