I learned this amazing C++ based GUI framework called "QT" (cute :)) in 2003. At that time it was owned by Trolltech. I developed UI for a Digital Cinema system which was used to project movies in theaters. Amazing framework to work with and lots of good doc for developers.
Screenshots would have been fun to see - I'm always fascinated by projects like these that are part of an industry-wide transition to something new. Especially considering you probably didn't have much or any prior works to guide what you built.
