After a while of walking around light containment zone, you come across some sort of machine consisting of gears, pulleys, and other mechanical parts. It has a large front panel and two booths, labeled 'Intake' and 'Output'. There are some words on the panel, seeming like modes for the machine. "Rough" "Coarse" "1:1" "Fine" and "Very Fine". There also seems to be a key that you can turn to start the machine
