The massive gadgetfest that is the annual Consumer Electronics Show may be over, but that hasn't stopped the unending stream of tech toys coming our way. We spotted some way-cool concept gadgets like the Rubik's Cube MP3 player, the fashionably high-tech Elio watch, and a sexy Sony Ericsson slider phone. There was some scary stuff, too, like those Dark Angel-esque RFID tattoos and the relatively undetectable metalless knife. Between headlines, we found time to pick our favorite off-the-beaten-path gadgets from CES and turned to microscope back on ourselves to reveal the devices that helped us cover the show.
