Looks like somebody found a job for their old Steel Battallion controller that didn't involve posting on small-time forums how much they paid for it or how awesome it would have been if more games had supported it.
Instead, Japanese VJ Bonsajo rigged his up for performances, using it to do things like fade and scratch the images appearing on screen. If, like us, you had no idea what a Video Jockey actually did outside of hosting obnoxious MTV programs, the video below may be of some assistance.
