Dance Dance Immolation

It seems like everyone who has friends who willingly play Dance Dance Revolution for any significant amount of time all arrive at the same joke, eventually: a DDR machine that will physically punish you for wrong steps. The object of telling this joke, in a group setting, is to see who can come up with the most amusingly violent theoretical machine, whilst still maintaining that small amount of plausibility.

Well, somebody has created a version of DDR that will launch celebratory flames into the air if you dance well, and SET YOU ON FIRE if you perform poorly. That's "set you on fire" as in "actually physically blast you in the face with a flamethrower." It was created, of course and oh-so-beatifully as far as us literalists are concerned, for the Burning Man festival. There's not much to the website, but you know what they say about pictures and how many words they are individually worth.
