SegaScope 3D
Long before the 3DS, even before the Virtual Boy, Sega had the SegaScope 3D for the SMS. It used active shutter LCD glasses that connected to the SMS card slot to produce a 3D display on a normal TV set. Without the glasses, the screen would appear blurry, with double images, but with the glasses, the playfield would become full-color 3D. Although far superior to Red/Blue glasses, the technology was not a huge success, and only a handful of games were produced for it.
Nintendo had a similar system for the Famicom in Japan, which featured games like Rad Racer and 3D Worldrunner. Unfortunately, that system was never released in North America.
