Well, OK I just invented this tradition, but it's a smart introduction and Life is one of the easiest games / cool animations you can program. But it's not too simple that we can't learn a few important things about JavaFX... My goal: a good-looking and feature-...

I understand Ian's pain as a teacher. Programmers who aren't curious, don't like to explore varied languages and paradigms, are doomed to rank-and-file roles. But this is secondary. The purpose of computing is to serve the needs of...
