A Pictorial History of Vista
I was actually preparing a similar post to the link below, and installing different Vista/Longhorn builds in Virtual Server, but it looks like I was beaten to it.
IntelliAdmin has a pretty cool post about the history of Vista (I guess you could call it a 'Vista-ry' :: waits for laughter :: :: continues to wait :: Eh? Aw, nevermind) throughout development. It doesn't have anything to do with Virtualization, but you should still check it out.
