Time to tackle 16. I could probably shave 30 or 40 cycles but I'd rather work on 16 tbh. I like that at one point every space has an atom in it. How is 16 possible, then? :azuripaw: I hate programming trackloops. Ok, where's the boardstate right when you're about to do the 6th product? 15 inputs have spawned, which is 15 air and 45 qs. You've outputted 5 products, which is -15 air and -5 qs. So, you have 40 qs left. That fits neatly into 8 golds. So, you have 8 golds (and maybe 1 lead if you pulled it early). TODO on 16: don't wrap the gold all the way around. shift through to the top, then walk it behind the bonder. DONE What does the board look like after the 4th product is delivered and the 5th product's first reagent spawns? That's 12 air and 36 qs, and after accounting for outputs that's 0 air and 32 qs, which is 6 gold and an iron.
