Mr. Marcin Wichary, currently the User interface designer, for Google, is the creator of GUIdebook. That have been online since 2003, so what's this site is all about, well to give you some brief description, i'll quote it from the author himself,
This site is meant to be an online museum of graphical interfaces, especially those old, obscure and in desperate need of preservation. Whether you want just to look back and refresh some nice memories from years ago, or are interested in seeing how the GUIs evolved throughout the decades (and it is sometimes fascinating to witness that)
Originally thought up as a comparison of various GUIs, it evolved into much more than that. GUIdebook features screenshots, icons and sounds, but also dozens of preserved archival articles, book reviews, vintage advertisements, interviews, trivia and posters designed by Mr. Marcin Wichary himself.
As for the questions "is the site still alive till now ?", well Mr. Marcin have the answers here :
The site has been updated regularely for the last two years, and I still try to keep it fresh and interesting by introducing new sections.
Well, then, as i already have permission from Mr. Marcin himself, i presents u some gallery of the screenshots ;) Enjoy :) (click the image to view the bigger one, note: took a while to load ^^)
