Very cool stuff. The seed lamp: it looks like two algorithms run at different scales (one for the large scale wrinkles, and another for the small scale porous structure). Presumably the large scale wrinkles algorithm run before the small scale algorithm?
I'm reminded of some 2d multiscale Turing patterns by Jonathan McCabe:
He runs algorithms at multiple different scales, but not in a fixed order. Instead, at each step it runs at the scale which has the least contrast, the aim being to make all scales have visual interest. He's got a paper about the algorithms here:
