Here’s an image I processed of the famous “Yogi” rock on Mars. The original images were taken by the Mars Pathfinder lander. Go cross-eyed whilst looking at the centre of the image to get the 3d effect.
This is my first ever stereogram and it’s made using exactly the same image for both sides of the “stereo input pair”, so it isn’t the best stereo image I have seen. I think I’ll have some more fun with this later and learn how to make good ones.
Thanks to these guys for the free software. And also to NASA et al for spending truly vast quantities of cash in order to take pictures of far-far away rocks (and other science stuff, of course).
