Nokia appears to have dislodged some huge creative blockage, beginning with its decision to back a new smartphone horse. Today we get yet another concept handset, revealed at Nokia Conversations. The GEM offers up an utterly customizable appearance that doubles as the interface. Following its naming convention, the user "polishes" the appearance of the phone, constantly tweaking it to suit their needs. The full-body touchscreen could offer up advertising on the back of the phone during calls, subsidizing costs, or media sharing done with some physical gesturing. See these glittering features shine in the ethereal design video right after the break.
