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.

Seriously, when was the last time you manually wrote PostScript? Programmatically?
It's like running across someone who decided to write a new GUI app in assembler.

I also like Forth.
As for GUI programming in assembler, it's been a little less recent.

Um... as soon as I can get any GDMF CS2 apps to open on my GDMF G5 again.

And okay, *I* haven't run across anyone using hand-coded PS in the past decade... good to know there are still some insane ones out there.
Shine on, you crazy PS diamond, you.
