    Thank you! As I was typing it I knew I didn’t have the right term for the ring bit.

    I’m going to ignore the fact I could have easily looked it up to fact check myself before posting, and instead use my age as an excuse.

    I was just old enough to remember my teachers using them, but the tech was already outdated so it’s not like anyone ever taught me about that type of projector, I only ever observed it.
