Track Designer

I'm not really working on this project (I need to try out Visual C++, but as of yet, I have not started using it) - but this is awesome. After years of being unable to update one of the most popular LEGO CAD programs for collaborative layouts - as well as a few competing software packages, including one where someone tried to reverse engineer TD - the Track Designer source code has finally been found. This LUGNET thread has the details. If you're new to all this, you're better off reading RailBricks issue 2 than anything else I have to say on the topic.
