Philip Terry emailed me another NASA picture of the day. This picture of Mt. Everest was taken from the space station, posted on the NASA website. Phillip said: “What’s the deal? I stared at this picture for a half an hour, seeing it inverted. I had to leave and go back to the computer to see it correctly. Then it’s really hard to see it inverted again.” This also happened to me! I first saw it concave, but after seeing it convex, I couldn’t switch again. It’s the same deal we had previously with embedded hand print. Be sure to check other similar illusions, like: Bjorn Borg, dragon illusion and Machu Picchu.
