My personal background is in advertising, so I still keep a close watch on what is happening in the advertising and creative worlds. One of the interesting developments has been a documentary called Art and Copy, a film about advertising creative and inspiration. It looks at the impact of some of the famous campaigns of the past. The director was also inspired by such films as Koyaanisqatsi (one of my favorite films of all time).
