Probably the most interesting document I've found on user interface design is the PDF from this site, discussing Do's and don'ts of user interface design. The funny part is that the site itself is named "Civil Engineering with Computing: OOP with C++, UML, and the STL" ... but this page does not contain any type of HTML title. Goes to show that we're all human. :)
