Cartography group Axis Maps continues their run of mapping goodness with the announcement of their typographic maps:
Created as a labor of love, these unique maps accurately depict the streets and highways, parks, neighborhoods, coastlines, and physical features of the city using nothing but type. Only by manually weaving together thousands upon thousands of carefully placed words does the full picture of the city emerge. Every single piece of type was manually placed, a process that took hundreds of hours to complete for each map.
Prints are available. Grab the large size for maximum goodness. They only have maps for Boston and Chicago right now, but hopefully the project continues to more cities. I'll be keeping an eye out for San Francisco.
