These images can be embedded on your Web site, e-mailed to friends, shared via Facebook and Twitter, and so on. Prints start at around $10, though you have to actually add a 3D photo to your cart to see prices. (Start 3D definitely has some rough beta edges.)

It costs nothing to register for Start 3D, and you can upload an unlimited number of images while the service is still in beta. After that, you'll be limited to 20 per month unless you sign up for a premium account.

I'm not sure what practical value there is here, but Start 3D is definitely a lot of fun.
