I enjoyed hooking everything up, even though it's a prototype with no real goals yet. Th UI was solid, even in weird cases where a bunch of lines overlapped. Very occasionally I wouldn't be able to connect as expected. I realized after seeing the screenshots that the intention is to use the dots, talldots, and flatdots to keep it tidy, but it's good that it's still usable when the wiring is messy.
If you scale this up, I think you might have to introduce some transparency if there's a lot of overlapping connections, but as it is, it works really well.
