Woah, that's awesome!
Yeah I went crosseyed to view the second one.
I've done some 3D photography before: basically you stand with your feet apart, leaning your weight on one leg,
snap the shutter. Transfer your weight to both legs so you are centred,
snap again.
When you upload or print your images, place them next to each other and cross your eyes. Bam. 3D images.
Sounds simple enough, but often you'll need to train your eyes a bit.
Go ahead and try it out next time you're mucking around with your camera!
