I opened wiby.me, clicked "surprise me" and got surprised!

I found GUIdebook Gallery, a (currently unmantained) collection of icons, screenshots, articles, books and other stuff on graphical interfaces, from Xerox Star to Windows Vista (the newest OS at the time the website got unmaintained).

Stuff there is highly organized and impecably curated. Screenshots, for example, are organized either by OS (Windows, BeOS, Machintosh, etc) or by GUI feature (file manager, dialog window, panel/bar, etc). The same for the articles, icons, books, and other things.

I'm browsing it since yesterday and am not done yet. High quality content.

I only knew one website with similar content (toastytech.com/guis).

What do you thing of this website?
Any page (screenshot, article, etc) there worth noting?
Have you found any other webmuseum of GUIs (or other related topic)?
Etc?
