Specially for the 500th anniversary of the Mona Lisa in about 2003-2006, this site features a newly discovered painting of Leonardo's famous lady as you have, literally, never seen her before. It's called Exit Mona Lisa.
There are also two animations showing her transforming, by different routes, into this rarely-seen condition, an original 3D stereo anaglyph picture of her normal self, an infinite Mona screensaver, and two seamless Mona wallpapers.
And, just for variety, there are some other 3D anaglyphs - conversions and photos - plus seamless anaglyph tiles, 3D animations, and anaglyph panoramas, in the Extra 3D section.

This is the home page of Mona Lisa Variations and also Anaglyphia.
Please click on any thumbnail picture above to go to that picture or animation.

The first three thumbnail pictures are, deliberately, very unlike the images they lead to.
