Well, having neat code is pretty useless in a game is you are going have
sync issues.
Furthermore, it's standard to have a game loop and a draw loop.
Plus, you are adding the overhead of using message queues. Also, if you
are launching or using a thread for each sprite the game is going to slow
down significantly from all the overhead.
