I recall once reading the creepy story BLIT by David Langford:
The basic premise is that images have been invented which when viewed have catastrophic consquences on the human mind/brain, effectively crashing it like a computer. The idea has cropped up in various different places.
I was wondering if there is any evidence that such a thing is even possible, for example has anyone ever invented/discovered an image that gives a person a really bad headache when looking at it. 
Trigger Epilepsy maybe.
No one could have an invented a deadly picture, or seen it, and then lived to tell about it.
They have found that for the cases of unexplained deaths, they often find the person has some history of epilepsy or siezures, way back when he was a child or sething, and end up calling it
Sudden Unexpected Death in Epilepsy.
For example, epileptics seem to drown more often, so it seems that just swimming could trigger an attack !
You should watch the deadliest python video though.
