Geeks rule.
I have a buddy who is teaching his young daughters math skills by... playing AD&D. Temple of Elemental Evil, no less. Srsly old skool. (They're loving it, btw.)
He decided he needed hex paper. He couldn't find cheap hex paper anywhere. He found pricey hex paper, but not cheap.
So, being a geek... he made his own. With proper numbering. And 30-hex uberhexes.
With PostScript.
And a text editor.

I am in awe.
