I did finally work around launching!
Started XQuartz (which I would anyway), but it didn’t connect. Tried in XQuartz’s xterm, which worked‽ Turns out it’s incrementing the DISPLAY each time XQuartz runs, DISPLAY=:1, DISPLAY=:2. So, I was holding it wrong.
I was able to put a bunch of stuff in the world, but the DI INFER button only updates the sharks feed humans cells?
I wish I could click to place stuff, then hit INFER!
Challenge: Very high (mostly getting it to run)
I want to play with this more, but the interaction mode is a problem.
