I won VIP thickets to Rock In Rio a couple years ago, and they had this in the urinals of the VIP area. It was supposed to show a stream of the shows but it just said server connection lost and a random local IP network (10.something) and there was an IT guy in the bathroom with a laptop connected to one of the urinals trying to fix the connection. I think it was the acid I took that day, cause I couldn't stop laughing at the absurdity of the scene.
