I was a child growing up in the 70's/80's and we were really fascinated by the seeming simplistic concept of the red and blue/green glasses (anaglyph) that help you see 3D images. My first real clear memory is of the free cardboard glasses that you got on cereal packets along with a 3D picture image to look at. The specific film promotion I'm thinking of was Jaws 3D, whilst I wasn't old enough at the time to see the film the visual idea has obviously lodged itself in my brain. I have never really stopped to think about how this kind of image is produced and I'm hoping it will be straightforward enough for me to research and maybe produce a still image or 10 sec moving image.
The purpose of this etude is for the sake of general artistic exploration, I'm not intenting to produce a masterpiece however it would be nice to produce something artistic. I would like it if I could produce something that could be a piece of viable art in 2D or in 3D with the coloured specs on. The reason for this is that if I was a commercial artist I would like to sell work I do and I think there is some limitation to producing just 3D work that requires the specs to look good.
Below is a picture of the great glasses you could get for free on cereal packets:-

So how is it done? How do the coloured glasses produce the illusion of depth?
