The first thing to do is get the anaglyph using the tiny URL found here after reading the article so you get an idea of what we are talking about. After have a lot of fun watching it with red-cyan 3D glasses:
- Put the glasses on upside down. Now you are looking at the inside of a mask.
- Create a negative of the anaglyph and look at through the glasses.
- Upload the image of Picasso or Flickr and look at it on a large screen TV.
