http://www.typebrewer.org/ - very cool site for interactively exploring different typefaces and sizes on a map. Not content to just show off, the site is also a significant learning tool. Did you know that the little bump at the bottom of a small serif "b" is called a terminal? Or that a serif font for large waterbodies like oceans for online display is good in the range of 13 - 20 pts while for print the same text's optimal range is 10.5 - 16 pts? Many thanks and kudos to Ben Sheesley of UW-Madison's Department of Geography for putting this excellent tool together.
