Since we're doing magic eyes now...
(sh.itjust.works)
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
Oh, also, I really miss the old JMOL molecular models that you could view in cross- or wall-eyed stereo. Anyone know what software is required to make those?
