After the official day one of CES 2008 I think this has to be my coolest gadget of CES so far, Guitar Hero Air Guitar Rocker, practice playing any place, any time.
Air Guitar Rocker is officially licensed with Guitar Hero but you don’t need to own Guitar Hero to play. Simply wear the supplied ‘heavy metal’ belt buckle, attach it to the included processor thingie and you’re good to go. Play your air guitar by strumming the plectrum in front of your groin the belt buckle and play such classics as Motorhead, Black Sabbath, Van Halen, etc. blast out and your adoring fans will stare at your groin in wonder.
