Design student Joonas Saaranen has created a backpack that is actually a speaker system. The hardshell pack contains both speakers and an amplifier for on the road use. (And I’m assuming a metric ton of batteries as well?). Pretty cool concept though I’m not sure I’d walk my streets rocking one. But bonus points for designing it to look like it came right off the back of a Stormtrooper. Just wonder, is there storage built in for an iPod? Or a six pack?
