I've updated the shader – I think the issue was just that I was initialising the states to random values instead of running a proper degree calculation. The behaviour looked pretty similar to me either way, but now it matches exactly and I added colours to make that clear: https://imgur.com/a/4gZKlSg

Looks closer. Can’t tell from your example if exact.. but seems better

share a link to the new version of your shader - would love to check it out

perhaps also make a version that starts from random initial condition as well?

looks promising
