So I'm sitting there typing on the computer, and out of nowhere I hear a pop noise. I look at the pinball machine, and not 3 seconds later the entire backglass shatters. The graphics on modern pinball machines are printed on a plastic translite, so it wasn't painted like in the old days. Still very odd. The machine was on and idling. I replaced it with some plexiglass or lexan, and reused the translite. The glass was tempered.
