[Halloween, 2013, updated link, Bing fixed the script code for pIqaD]
People have asked me where to get a pIqaD font to use with Bing's Klingon Translator http://www.bing.com/translator/?from=en&to=tlh-Qaak&text=Hello%20Earth,%20I%20made%20the%20font
That's actually a font I made. (I'm not a font designer, so it has some rough spots, but it seems to work for most purposes).
The pIqaD font is licensed under the Microsoft Public License (MS-PL).
I've attached a zip with an updated version of the font. Both a ttf font to install locally, and a woff file if you want to embed it in a web site. It's called "pIqaD", so you'll have to pick that to use it in Word or whatever.
