Mathematically the main idea is: we start with functions l (or lattice): R^4 -> R and t (or transformation): R^4 -> R^4. Then we visualize a level set of l o t.

A note about the rules:
In order the viewer to get a better visual understanding of what is going on in this animation more than 100 frames are necessary. There is no rationale for the “exactly 100 frames” rule on the Paul Bourke’s website. To my knowledge such restriction does not exist in the demoscene for the size-restricted intros. To some extent the same apply to the 400x300 resolution restriction.
