Sanwa stereoscopic YouTube viewer turns your iPhone into a big-screen 3D TV

Japanese iPhone owners are being given the chance to bathe in the nostalgic glow of the old 3D View-Master -- only now, the pictures will actually move. The Sanwa device works in a similar manner to its ancient mechanical counterpart, but magnifies side-by-side yt3D YouTube movies on an iPhone instead of the classic circular slides. On top of negating the need for custom content like similar products we've seen, this should also yield a brighter and larger 3D viewing area than red-green glasses -- letting you get the most out of that retina display.
