I needed to know more about the numeral characters in different scripts.
I googled my way to yet another Unicode summary, where I became stuck for awhile, and went on to buy a book linked from there.
Kept reading, got down the the link to Unicode's allocation pipeline.
From there, reading about:
Shavian: http://www.unicode.org/pending/shavian/shavian.html (font)
The Phaistos Disk: http://www.unicode.org/pending/phaistos/Phaistos.pdf
And from that document, onto the Klingon Language Institute (http://www.kli.org/).
I've always heard of dorks learning Klingon, but I never realized it was designed by a professional linguist, so I kept reading... found my way to the Postal Course lessons.
I skimmed a few lessons until I realized: goddamnit, I'm trying to work right now. And what am I doing reading about Klingon!?!?
I hate you, Internet.
