When I got this tip, I was skeptic: Anaglyphic 3D porn never worked for me. But for some reason, this one does. You just need the classic red and blue eyeglasses. And some other accessories, if that's your thing.

I don't know why this one works so well, but it's really cool. Maybe it's the annoying intermittent graphics. Maybe it's the kinky 80s photos. But it works. [3Dporn NSFW—Thanks Richard!]
