Grey curtain of death.

I'm sure many of you are Mac users. Even if you are you may never have seen this. It's related to, but very much rarer than the PC equivalent, the blue screen of death. Pictured is what you see if you drop a shelf unit (don't ask) on your girlfriend's Mac laptop and contrive to knock out a few of the components on the mother board. £400 to fix or £350 to buy her a second hand iMac. Now if I could just put my hands on £350 all would well in the world.
