The Universe Machine is by Joshua Davis (praystation). It is a flow field of approximately 56,000 instances, with bit-exact cubic-bezier arc-length sampling.
I translated it to Solidity on the Kohi engine. The port uses the same XorShift stream and bezier math, and makes the same output.
Here the metadata moved on-chain. The tokenURI returns the metadata as a
data: URI. But the image field points off-chain. At first it pointed to
the kohi.art API. Now it points to IPFS, so the image does not need Kohi’s server.
