Sony went seriously 3D-crazy at CES
this year, and in addition to the slew of shipping 3D products
, the company is showing off some futuristic prototypes -- including this 3D head-mounted display that features a 720p OLED display for each eye, simulated 5.1 surround audio, and super-slick blue LED piping. No price, no availability, and no practical functionality since there's no way to keep the thing on your face without your hands, but c'mon -- you know you want one. Video after the break.
