I saw that. Someone out at a company my dad had as a client when he worked at honeywell, someone jammed a pencil through the LCD when they got mad. After pulling it out, the screen worked as usual, except there was this small mark and spider cracks going out from the pencil area. In fact, except for the small hole where the pencil went through, even the panel behind the spider cracks were displaying. It was the weirdest things, which makes me wonder if there was a hard glass/plexiglass panel in front of the actual LCD that was designed for a buffer. Keep in mind that this was a heavy duty LCD monitor, and was built for hard environments, but it's weird as it looks like it want all the way through to the difuser panel behind the LCD.

Truly an oddity but hey! it still worked!
