...not good.

Isn't that a transistor or something going out? I forget what causes it, I'm not sure if massaging at a certain place will possibly make it go away like some dead pixels. Have you gone to the knowledge base on apple's site about it? It isn't an Apple only thing though, I've heard of this happening to LCD's.

it's likely a cracked video cable. often times pressing on the hinge in the lower left or right corners will make it go away.

you can order and replace the cable (since your machine is likely out of warrenty anyway) but they're extremely delicate, so it's not the easiest thing in the world to do.
