A fellow by the name of Chris Marion modified a Guitar Hero controller to interface with valves attached to a propane tank.  In his words:

I thought of using a microcontroller to sync the fire to the beat of music – now that would be pretty cool, and the patterns would always be different, so it wouldn’t get as boring as fast. Then I thought of the game Guitar Hero, which uses five frets, and I had my idea! Simply interface a Guitar Hero controller to a microcontroller that would power some relays which would in turn fire off solenoid valves on five individual fire poofers! Now this could be cool; a large fire “sculpture” that is playable by anybody.

Head over to Chris’ website to follow his instructions if you suddenly feel the urge to construct your own FireHero.  For Version 2 he’s planning to introduce color-changing flames, Star Power (“which would boost flame height or fire off additional fireballs”), and play “Through the Fire and Flames.”  But for now, enjoy his inventiveness in the video above.  After listening to AC/DC on fire, hop after the break to watch Motley Crue’s “Kickstart My Heart” in action.
