I wouldn't be surprised if the Wx version were a bit longer. Wx offers 
more flexibility at the expense of making simple things a bit longer - 
for simplistic apps, Tk, or Shoes, are often better choices.

It would be useful to define what the script is expected to do so that a 
proper comparison could be made - for example, is the timing of the 
animation specified, b/c I can't see how this is done in the Python/Tk 
version.

Anyway the version below does the same as your version in < 50% of the 
code. If I jammed lots of things onto one line, like the Tk/Ruby version 
it could be shorter...
