There was an Apple ][ game that did something similar. I think it might have been King's Quest. In the era when people used hole punchers to make flippy disks, if you accidentally put the game disk in your machine upside down, the game displayed upside down.

Today you can make any Mac's display turn upside down with a few clicks in System Preferences. Someone in my office may or may not make this happen on machines that haven't been properly logged out when someone goes on vacation.

(A quick Command-Option-8 is also good for some fun.)
