yes. There really aren't truly global variables in Python the way there 
are in other languages -- and that's a good thing!

Even if it just for that module -- I still feel like it's kind of ugly 
-- and you now have to change code in two places if you add new bitmap 
-- once in your code where you use it, and once in the import statement.

Also, in the code itself it's not obvious where that variable came from.
