Well, I don't, really. But I have had difficulties in implementing
my ideas: when Brian gets near the edge, scroll so that he gets in
the centre, but don't do it in one giant step but in 10 small steps.
The problem being that Brian moves in those 10 frames... but this
problem is solvable of course.

Well, that depends on the resolution the user chooses. On 640x480,
this is already more than on 800x600, but then, it is also cheaper
to move around the screen...

Yes. I would think that, because pygame is written in C, I would not
have the penalty for using ahigh-level language, but I am probably
mistaken.
