iMacs!
Turns out that one of the iMacs I was going to get had some power supply issues. Whatever, seven displays was the random number I picked out of the air to begin with.
Also: it's come to my attention that while people have actually seen this blog, no one bothers to download the Proposal PDF that explains what the whole thing is about. So, instead, please have a look at my brand new Flickr page! The terrible low-res photos I keep posting are from my webcam, I should really get a digital still camera.
