David Macaulay: All roads lead to Rome Antics

http://www.ted.com Despite a love and fascination for Rome dating to his days as an architecture student, David Macaulay found the path to his book Rome Antics took some unusual (and frustrating) turns. Through failed pop-up designs, scribbled out title possibilities, surreal sketchbook pages (think "Piranesi meets Escher"), and rambling story lines, Macaulay details each step of his winding journey towards completion of his illustrated homage to the city.
