Great GUIs of the Past
Talk a walk down memory lane with this slide show from CIO.com. It traces how the desktop GUI has changed over time. Starting with the very first GUI—Xerox's Star which debuted in 1981, it includes pictures of 1984's Macintosh GUI, Amiga, Windows 1.0, OS/2, Windows 3.0, Mac OS 7, Windows 95, KDE, Gnome, Windows XP, Mac OS X, Windows 7, Windows 8 and others.
For developers, it offers an interesting look back at how interfaces have changed over the years and how they are continuing to change today.
