The Spirit probe on Mars sent back some funky 3D, stereoscopic images, one of which is up on NASA’s web site today. The space agency helpfully provides some viewing instructions:

This is a cropped view of the first Navcam stereo mosaic from Spirit at Gusev crater. To see the image in 3-D, you will need to obtain a pair of 3-D glasses, with red and blue filters over the eyes. The glasses are often available at comic book stores.

Man, there is nothing more purely superb than NASA urging you to go to a comic book store. I can’t wait for their next bunch of announcements. “If you wish to fully enjoy our 40-page report on the potential of life on Mars, you will need to be wearing a pair of Spock ears. They are often available at Trek conventions.”
