If you like some creativity, you should check this out.
Microsoft directly jumped from Windows 3.x to Windows 95, but now there is a web version of the Windows 93, which you can enjoy. This web version works actually, there are some small apps including paint.
These is also an app called Zkype with a Skype logo turned backward, but good for nothing and useless. There is also a browser with some bookmarks folders, and it works. You can find a nasty bookmarks folder and I found this bookmark (penisland.net) , but it does mean something else, check it out yourself. 
So, you can just take a brief tour around and waste some time. It is an innovative idea of course, but not useful for any job.
