rough mesa
In the garden of the art event, you can click at the floor reflection of the human figures next to the photography showcase, and the camera goes under the floor to focus on its reflected version, turning everything upside down. The click area seems rather small, but I can reproduce it semi-reliably.
Clicking elsewhere restores the default camera position, so it doesn't break anything. You can even use camera mode to peek back above the floor. I guess it could be an easter egg, but I'm reporting to be sure.
