It took me 20 days to develop. Perl/Tk.
If memory service me right, and I really could be wrong .. I think I must have been the first one in the world to hack together a bridge between Perl and Office 2000, because I had a developer preview. ActivePerl .. now that was a delightful platform.
Perl empowered me. If it wasn't for Perl, I might have quit software altogether and became a philosophy major, or worse, a mathematician.
