WAVE RECYCLER

The first one is a defected van berlo's wheel

great fun solving this one https://i.imgur.com/VSmX0jU.mp4

I was trying to improve on the area, mostly, but when the start point isn't heavily optimised it's often possible to get more than one metric reduced at once. Optimal solutions in each category are likely to look different, but sometimes it works out as it did here.

@Darael: Interesting to think about minimizing all 3 values at the same time :) I usually focus only on one of them, and build 3 different solutions for them ^^

Some minor tweaks to Alcator's solution (six-arm to a single on a smaller track; remove the middle calcification glyph because only salt passes over it anyway; shrink the lower track by three units by crossing arms and moving some things over) get it down to 340/94/219. Could definitely do better in cost or speed, but any significant gains in one will come at the expense of the other and probably also some area.

@Alcator: Thanks :) Any gif solution to share?

Interesting puzzle! :-)
