You'll have to find a pair of red/blue cellophane glasses to enjoy these. (okay, I know you have a copy of SpyKids 3D! Find the glasses there!)
I used these old NASA instructions to make 3D images. Try it out and post them up here!
These are some of the ruins found in Palenque, Mexico (I accidentally filed as MonteAlban). Pics taken the summer of 2005.
