Agree that’s pretty cool. i would like to see if the speaker would survive if you actually scrubbed it in!
on a side note, many OR staff have gotten in deep trouble for taking and sharing photos with any part of a patient visible. i would consider taking this down.
To the other poster who mentioned it - Don’t sweat the photo: only shared data (photo) that is a problem under HIPPA is that which is attributable to or identifies a specific individual.
