Here's a charity item we guarantee no one has ever auctioned off before: a Guitar Hero controller bonded to a skateboard fragment -- with Tony Hawk's siggy, no less. Bidding starts at $100 and proceeds go to the MusiCares organization, which catches panhandling musicians in a delicate safety net and provides them with "critical assistance" (read: not a record deal). Some 29 other celeb- and rocker-decorated GH controllers are also up on eBay to support the cause.
For anyone hoping for more than just a geeky display piece, please note the fine print: "Owing to customization, the controller is offered solely as an art object and is not guaranteed to have retained any functionality; buyers who choose to connect the controller to a console do so at their own risk." (Ever seen a skate-guitar asplode...?)
