There is another company that offers similar modular systems up to 16 monitors. Not sure who uses them, financial sectors often have up to 8 and just stack the damn things, way cheaper.

Mitsubishi makes flat-panel and almost-flat projection big sets that will stack like that. I saw them on display at the CeBit show in New York last week.... very impressive, even close-up, which is where a lot of big screen sets start to look crappy.

Yup
 

Yeah Perth, lcd's suck when it comes to gaming basically because of the refresh rate. Everything looks fuzzy cause the screen can't keep up w/ the data its being fed. Thats assuming you have a decent video card that will supply the framrates to notice this.
I run a ATI 9800 pro 128mb and tried my buds 17" Dell lcd and i nearly cried for my 20" crt back!
