In Primary School there was a traffic light on the wall of the cafeteria. If we started to get loud it would go to yellow...really loud and well I think you can guess. Clowns rode out on unicycles and shot us with paintball guns. OK it just turned red. The clown thing sounded way more interesting.

Not sure if it was some noise sensor, or just someone with a remote or button of some sort, but I still think it was a good idea. Unicycle clown paintball patrol is better idea though. }

I collect Macs and old telephones and related equipment. Also in college I used to collect parking tickets due to a total disregard for campus parking policies. :lol:
