Alternative, smaller, simpler logo based on super-helpful feedback from Aaron Parecki, Brian Suda, Brennan Novak, Kartik Prabhu:

I kept the multi-stranded green connection as I couldn’t find a single green which looked effective on it’s own, and the whole thing was so much flatter without the extra depth they give.

Also, an alternative version with randomly truncated segments – symbolising sites with different levels all interacting happily

which was worth a try, but I think it lacks balance. Probably going to stick with the first one.
