I know this isnβt exactly a gadget, but it sure is eye catching. Itβs a collection of 3D car replicas that double as shelves for your wall. Made of resin and glass, these colorful front bumbers of some classic car models from the 50βs, 60βs and 70βs would be perfect for any man cave (or hey, a girl cave if youβre a female car nut). The price isnβt bad either at $89.95. They are available now from Gadgets and Gear.
