There used to be this thing going around on pre-smartphone phones (via Bluetooth, I assume) that showed a pocket watch closing and when it was fully closed, the phone shut down. We all thought it was hilarious to send it to as many people as possible and watch them panic. I don’t even know what format it was to look like a normal gif or video and do that. I certainly didn’t even care back then.
Well, I sure hope that’s not where visitors are supposed to walk because that barrier wouldn’t stop a blind turtle from escaping.
