Earlier this week I started browsing some sites on GUIs and found several references to Chiacgo - the development codename for windows 95. I did not now this but there are sites with screenshots form some of the earlier versions, as well as links to the actual versions.

For some strange reason I found this oddly fascinating - looking at some of the earlier developments which were between 3.1 and 95. It's kind of like going back in time and watching the house you grew up in being built.

I may be wrong about this, but I believe that at no other time did Microsoft do so many early releases and solicit so much feedback during the development of an operating system.
