Here is a fun  but totally useless script I wrote which converts webpage images into pseudo 3D images, using the old anaglyph-3D print technology which was invented by Wilhelm Rollmann in Leipzig. It consists in overlaying two stereo images, one using only the cyan channel, the other one using only the red channel.It creates a 3D-view through red-green glasses. The script can either use two stereo images, or create a fake anaglyph.

There is also a Chrome extension, which transforms every website into this 3D view. It does not work on background images though.
