Chank's Free Fonts
Modern font design can't be discussed without mention of Chank Diesel. I first discovered Chank fonts via a link from Jeffery Zeldman, probably not long after Chank came online in 1996. Beginning with 1999, Chank hosts an growing collection of annual recognized free fonts. The latest offering, stemming from a teaching gig at the 2004 AIGA Design Camp include three unusually floral fonts derived from three Chank staples. Browse the collection of fonts new and old to add creative typography to your desktop toolset. Commercial use does require the appropriate license for the fonts.
