vroomboxLet's face it: you're probably not going to get that macho roadster you always wanted. But at least your current ride — even if it's a mere minivan — can sound like a '71 Barracuda, thanks to the Vroom Box. Currently under development, the Vroom Box is essentially a digital engine-sound generator that you sync to your own engine. Hook up a set of speakers under the car, and you're set. Sure, it's a cheap gimmick. But we have to admit, at some level, this appeals to the kid in us: it's the adult version of sticking playing cards in your bicycle's spokes to simulate engine noise.
