I have submitted my first app. More useless than the fart app. It is called Old School, and you can read more about it in this thread (or just find it in the Desktop category of Extras-Devel). It is a Python app (PyQt), and I am hoping to write up a short primer on packaging a Python app so that others don't have to spend the two days I spent googling, downloading, testing, and struggling (and so people who actually know how to do it can correct me as well).
