Stereo 3D
 
This stereo pair of images shows Ianis Vallis on Mars. The images are from an animation sequence generated for a GeoWall stereo projection system, which is viewed in 3D using polarised glasses. To view the scene in 3D without polarized glasses, sit back from the screen and try to merge the two white dots into one, then relax your eyes to focus on the terrain.
