No problem, Simone. I also share your observations: we can't learn much of this stuff at work. We have to do our jobs, plus just a little bit more.
That project is called LaunchMFD. It's an essential navigational tool for Orbiter Space Flight Simulator and can be found here: http://www.orbithangar.com/searchid.php?ID=2802 On the left panel, links "Most wanted" and "Highest rated", you can see that it's quite popular. I also do car navigation software at my daily job, and the LaunchMFD helped me to get the job, and helps me during the job in both experience and direct reuse of code. Here's a note for you Simone - well Object Oriented classes can be used not only in your fun, private projects.
So for all you trolls out there, who think that all I can do is draw some "matchstick graphics", think again.
