This air guitar defies convention by not being made of air at all, but it’s still an awesome idea. It was designed by Julien Duquesnoy. The iRock is basically a guitar frame with a spot in the center for your iPod. See where this is going?

The neck of the guitar is a speaker, so what you have is a complete self-contained instrument of rock. The iRock is constructed of lightweight aluminum and would fit the iPod Classic and iPod Touch. It’s just a concept right now, but we can see this thing being produced and selling well.
