Over the past few years, the videogame Dance Dance Revolution has become a phenomenon. Featuring a pair of four-paneled dance pads and a library of uptempo rave tunes, DDR has taught thousands of otherwise ungainly geeks how to "dance" without leaving their comfort zone of the local arcade.
DDI is much the same animal – with a twist. The game's creators, the Bay Area group Interpretive Arson, hacked an open source version of DDR called StepMania, then added a 12-foot projection screen, supersize dance pads, and, just to make things interesting, nine propane jets. Screw up a dance step and you get broiled with 3,595 degrees of flaming propane.
