Here are the links to the main page of each module (rather than directly to the tarballs):

• Lingua::CS::Num2Word
• Lingua::DE::Num2Word
• Lingua::Num2Word

Definately cool, if you run the following example from the docs:

use Lingua::Num2Word;

my $numbers = Lingua::Num2Word->new;

my $text = $numbers->cardinal('en', 123);

print $text || "Can't convert number\n";

It'll print out "One-Hundred Twenty-Three." I like it :).
