From Gamertell:
"Super Stardust HD in 3D was one of a few 3D games Sony had on display at CES 2010. The setup featured one controller with three pairs of 3D glasses on each side. This allowed one person to play the game and two others to watch. These glasses were the same ones Sony had the audience put on during its press conference the previous night. When I put the glasses on and started playing, I instantly saw a difference."
