I made a 6 bit binary counter. It counts the number of times the mover cell goes through it. Each of the yellow slider cells represents one bit. when they are spinning the value is 1, when they are not spinning, the value is 0.
Happens with every blocky game, I swear. minecraft, mario maker, and now cell machine. edit: I saw your other comment and someone called you sam hogan himself and now I have conflicted feelings
