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
At my work, we maintain computers for a bio lab that use Nvidia glasses to view stereo images of cryogenically frozen protein structures.
Nvidia doesn't support them anymore, and there was an email thread that was forwarded to us by the lab manager of some scientists discussing the issue. One of them suggested to the others that they could just cross their eyes and see the images that way instead of using the glasses. Funny stuff!
