Oh yea I’ve used it and from memory it’s awesome as you say. I was more talking about getting into the technical details of running a model and calculating various things of personal interest.
Me too! Always wanted to get into, thinking it worthwhile to have a running solar system or celestial model on your own machine that you know how to operate etc. Just never really tried sadly!
It’s wonderful to see how even at this scale there’s still that fractal-ish, dense and chaotic, but elegant and beautiful aesthetic that nature creates.
