Check it out...A group of enterprising modders in the UK have sucessfully hacked Guitar Hero to be controlled by soccer...YES, SOCCER.
The Football Hero game is a standard Guitar Hero game in its display, but the control has been rigged to 5 pressure sensitive squares that trigger a specific key when struck with a soccer ball. Sooo, the Guitar Hero song begins, and 5 soccer players kick balls at precisely timed moments to trigger the pad that corresponds to the key on the screen ! Sweet!!
