I was having a discussion with a friend and he had a fun idea.
A partitioned room. It is apparently something F-list has.
The idea is, you would enter the room either through the “giving” or the “receiving” entrance. People inside either room can see/hear actions from the other side, but not who. Rather than show as a name, they would show as “voice 1” or something along those lines.
As you might guess, this is intended for glory hole and “stuck in wall” play…
I do not know what coding wolfery uses, but making something like this should be possible.
