Anaglyph for 3D video

Anaglyph is the technical name for a technique of making images that have a stereoscopic 3D effect - so rather than appearing flat like a picture they appear to have depth like objects in the real world.

The anaglyph technique uses glasses with coloured filters to make it so that each eye sees a slightly different view. You can read up on how they work and how to make them yourself on Wikipedia. It's actually quite easy with modern technology, but the technique is quite an old one.

There are applications outside entertainment, and anaglyphs can be used help visualisation in science and design. Examples include viewing microscope images and models of chemicals. You can see some anaglyph photographs in the 3D gallery on the firrs webpage.

This video is mainly a bit of fun, but it shows how the anaglyph technique can be used in moving images. You can watch a much higher quality version here.
