I set one up for a buddy of mine about six months ago for a display function that has was giving at a convention. Get yourself a video wall controller (we got one from eBay for $180). That and the correct software and you're good to go for whatever you'd like. We ran a 16 cube display with a laptop.
There are several software products that you can work with also. For our setup we used Datapath:

You may need a multiple monitor setup software also. I don't know what you'll want to do overall. You might try this one to help out:

A little geek tinkering and you might find you can do even more. Hope this helps!
