I was surfing around today and found this company and their insane monitors. I can't afford one now, but maybe some day! Can you imagine what you could do with 19200 x 2400 pixels of space? http://www.go-l.com/monitors/athens/features/index.htm
Thats pretty neat, I can imagine that would be quite useful for people in industries that deal with things such as the stock exchange. When you see one of there setups they usually have a fair few monitors.
