I loved traipsing through the different fonts to see what they did. I discovered some font-features I wasn't aware of:

* bitmapped + ligatured fonts - you can have both!

* sans-serif normal, serif italics - Italicized words were serif-ed. "Latin Modern Mono" is an example. Also, Donald Knuth made that font - did you know Donald Knuth made a font?

Really cool work, thanks for making this.
