Karl Sims's 1994 demonstration of evolved virtual creatures: block-bodied creatures whose bodies and controllers are evolved through selection, mutation and recombination to swim, walk and compete.

HN treats it as the classic reference for evolutionary simulation and genetic programming, an inspiration for many projects, with notes on evolution exploiting simulation bugs.

Also relevant is Karl Sims' Evolving Virtual Creatures: ▶ this video Not sure how they're connected, but I remember being obsessed with that paper and actually recreating it in 2D as a grad project.

Something like evolving virtual creatures would be a fun (although pretty ambitious) addition [1]. There's a processing 2D virutal creatures model called sticky feet [2] (source available) that perhaps could be ported to js pretty quickly. [1] ▶ this video [2] link

I think evolution is not an undirected process in that sense because it's an optimization process, that optimizes to create more copies of itself. Superintelligence will likely use some Evolutionary Computation (see en.wikipedia.org/wiki/Evolutionary_computation ). Also see Karl Sims 'Creatures' from the 90s: ▶ this video or OpenAI's Multi-Agent Hide and Seek: youtube.com/watch?v=kopoLzvh5jY

The article's philosophical discussion of "surprise" feels a little klunky and academic to me, and I think conflates some different kinds of surprise, but it's still really fun to think about. Many of the projects here are all inspired by Karl Sims' work in the early 90's. link Sims evolved virtual creates by specifying goals to achieve and then running a physics simulation. He noted at the time that the evolution process was great at exploiting bugs in the simulation. ▶ this video I was insipred enough by Sims' genetic images ( link ) that I spent a few years trying to get surprising and beautiful results of my own, with some limited success ( link ).

I hadn't before, thanks for the tip! It's been a while since I played with this stuff, but I might have to get a copy and explore. I have heard of MetaSynth in audio circles. I'm not sure, but the images and videos on the ArtMatic site look (to me) very inspired and influenced by the work of Karl Sims, which is the main source of inspiration behind my project... link You can find a bunch of his videos on YouTube too. link link link ▶ this video
