My time has come!
The above stereographic image is for cross-eyed viewing (most stereograms are wall-eyed, so you may need to put your finger in front of your screen until this one comes into focus)
This is an image of Honolulu, Hawaii, published by NASA. Note Diamond Head (the volcanic crater) in the south.
Here are some other stereopairs published by JPL:
Wheeler Ridge, California
Mount Saint Helens
Salt Lake Valley, Utah
Wellington, New Zealand
Yeah my eyes are prolly not used to crossing or something. When trying the finger thing to cross and merge the dots in the middle, it does works but it hurts to much to keep it stable. Will give it a shot on my PC later. I did toy a lot with wall-eyed ones years ago, so I intuitively started doing that until I noticed a lake on top of a hill in the third one :')
I did end up posting the wall-eyed version of some of them in a top-level comment.
