  I don't know much java, but have done quite a bit of C++...I shudder to
think about the C++ code I'd have to write to even do what I've already
done, let alone when it finally garners a pygame-enhanced UI...The other big
project happenned to be another game, which I wrote for this company in
tkinter (I'm a uni student and I work at this company in the breaks - this
game however is just for fun) ...it was initially just to show how versatile
the tkinter library was but when they saw the little pong-like game, they
wanted the game instead of anything else I was making.  Ended up growing to
silly proportions :).

  Yep, sure can.  I was just fearing stepping into any namespace holes of
'well, there goes three hundred lines of coding...' and it turns out I
almost did...thanks alot for your help!
