I learned today, in this article and some other related research, that a second Mona Lisa painting is suspected of being another side of a 3D experience. If anyone could pull this off, it would be Leonardo DaVinci. I focused my eyes between these two pictures and was able to see a 3D image. See if you can do it.

It is suggested that he initially painted both simultaneously:

Difference: German reseachers discovered there was a slight perspective shift between the artworks - with the painter(s) having created them from different vantage points of around 2.7 inches in horizontal distance

Study: The researchers used a red-cyan anaglyph to combine the two paintings of the Mona Lisa (pictured) 
Here are the faces. See if you can trick your eyes again…

Hint: If you can’t warp the picture to 3d with your eyes, make the picture smaller until you can.
