The folks at Juicy Bits (http://www.juicybitssoftware.com) have come up with the 3D Camera an app that lets you create 3D photos with the iPhone.  Sure, it's a cha cha system, but it still works so folks with the iPhone can create anaglyph (red-blue glasses) or parallel pairs or even wiggle style autostereoscopic images and then send them to friends or post them on twitter ow whatever.  There's a gallery of sample images on their twitpic archive at http://twitpic.com/photos/3dcamera . . . so, those of you who have iPhones but don't carry your 3D rig with you every where you go (and why wouldn't you?), have fun.
