Gaah, obviously it should have been just http://mg.pov.lt/pyspacewar/
Copying and pasting URLs from Firefox to GNOME Terminal sometimes has
this strange delay that makes me thing I didn't press the middle mouse
button, so I do it again.

Model objects have no references to view objects.
You can take the Python modules that implement the game model of
PySpaceWar (world.py, game.py, ai.py) and build a different user
interface without changing those modules. Or build a network server
that doesn't have any drawing code. In theory. I haven't attempted
either, so it's possible that some flaw in the design may require
modifications to the model classes to support alternative views.

It's the programming equivalent of putting your answers into the
original math equation to make sure you haven't made any silly mistakes
while solving the problem.
Dive Into Python has two chapters devoted to unit testing (and
test-first programming, which is a somewhat separate thing):
