No switch to be flipped. Already used that way.

Atlanta has them in the middle of parks too far from and facing away from parking lots to read any license plates… they’re there to use facial recognition on children playing on park equipment.

I sometimes find when you do this, ask how someone’s doing outside of the initial small talk bit, they seem to find it more genuine and will open up anout how they’re actually doing. When I’m working and someone greets me with :how are you" or “how’s it going” I’ll usually answer something ridiculous like wonderful! And not ask them back. If we’re still working chose by, a bit later I’ll ask how they’re doing.

I think if you poured that from the back of the skull there aren’t that many undercuts except around where the jaws meet. Still likely a 2 part mold but nothing overly complicated and putting the seam around where the jaws meets alleviate the undercuts there as well as helps hide the seam.

Or it could be a single metal mold utilizing the size difference after heat change to help release. Still poured from the back which we don’t see in the pics.
