Our sister site DVICE discovered a collapsible guitar peripheral for all your Rock Band and Guitar Hero needs (excepting vocals and drumming). DVICE suggests it will save space in your home, which makes me think they haven't had to deal with multiple drum kits. Wake me when someone invents a drum kit that fits into that little cloth bag.

Also, I have scientifically determined that rocking out with that...well...thing that isn't quite a guitar is precisely 34% less cool than rocking out with something shaped like an actual guitar. However, the act of assembling it, which reminds of the scene in a movie when the assassin has stealthed onto the roof of the adjacent high-rise and is assembling his bad-ass sniper rifle, makes you look 44% cooler than a guy with a toy plastic guitar. So, on balance, DVICE has potentially made me look 10% cooler.
