I could take incredibly realistic 3-D photos with my Incredible! I'm not kidding either, here's how:
The Incredible's got those dual LED flashes, that's the key. Easiest way would be to slap a little red gel on one and a blue gel on the other. Then you take a photo with flash, and toss it into photoshop so you can separate the red/blue channels.
Since the LEDs are so close together, the photo probably won't show significant depth right away. But with some fancy triangulation (we know the distance between the LEDs and can measure the distance to objects) you should be able to amplify the separation between the channels to get the appropriate relative depths of objects in the frame.
Toss on some classic 3-D glasses and BAM, you're in the future! The future looks incredible! Heck, with that burly snapdragon processor, you might be able to whip up an app that can prep the images on the fly.
Also, if you can gain access to the flash controls through rooting you can do this without the R/B colors, so it'll work in real color with polarized glasses. Take one shot with the first flash, second with the other. This would have to be a still life to prevent movement between shots, while the R/B method could be snapped anywhere. Then you can amplify the separation of objects between the two photos in photoshop again, polarize each image and BLOW PEOPLE'S MINDS!
