The notion of making trash into furniture may not be appealing at first, but take a look at Rodrigo Alonso's n+ew (no more electronic waste) "stool-sculpture-installation"s and you might change your mind. Made from e-waste (electronic waste, ranging from keyboards to various wires and cords) held in epoxy resin and aluminum, these stools are the perfect addition to any geek's sitting room. The cluttered look of the mess inside is a nice contrast to the sleek shape of the piece itself.
Check out the rest of Alonso's website for more interesting designs. I'm terribly fond of the B + W dishes.
