Thank you so much! I tried solving it after only reading "pick a rock from the table" but The meaning of the numbers on the disk were too confusing. I thought my task was to find outer numbers in the room so I know how to align the inner numbers and didn't even begin calculating, assuming the binary matrix on the right would have to do with it. Then I was worried the buttons underground were a puzzle too so it took me a while to start switching them. i was clueless for a while but after staring at the google result of a oil rig I finally realized what the password might be.
