[Jprogramming] Running a video game loop

If you are interested in programming rudimentary complexity video
games in a purely functional style, maybe you would like to spend an
hour or so reading this blog:  http://prog21.dadgum.com/37.html
If you are not, then spend a couple enjoyable days on it.
