"It may seem like 3D sprung from the ashes of discontentment -- not to mention red / blue glasses -- but Nintendo never stopped believing. It's been secretly refining stereoscopic tech for years in the likes of the Game Boy Advance and GameCube. And while president Satoru Iwata already mentioned early last year that the GameCube had hidden 3D circuits, he recently revealed that the 3DS's autostereoscopic panel actually dates back to the clamshell Game Boy Advance SP. Which, as you might recall, also once sported a touchscreen. At the time, his story goes, LCD resolution was too low to generate a sharp image, but the optometrist-friendly glasses-free tech was already in place. Of course, if you truly want to consult the history books, you can consider Nintendo's entry into the market to be the Famicom 3D System shutter glasses pictured above... which hit stores in Japan way back in 1986. Yeah, we know."^^<http://www.w3.org/2001/XMLSchema#string>
