When USB flash drives first came out, they were useful, expensive and valued things. Nowadays they're still useful, but I've got a drawer full of them, as every press conference I attend passes them out like candy. Most are made of plastic, some of metal. As they continue to proliferate, oughtn't we make them out of recycled/recycleable materials? BOLTgroup thinks so. The North-Carolina-based design firm is trying to Kickstart Gigs 2 Go, their project to release flash drives with bodies made from recycled paper pulp. The idea is that users buy them in credit-card-sized four-packs, and tear them off as needed for file sharing.
