Pharrell Williams on "Piece by Piece" and his love of joy

On a rainy day in Paris, Pharrell Williams was at the headquarters of Louis Vuitton living the dream, at an office he prefers to call "a dream space."

Last February, Williams was appointed the Men's Creative Director. He oversees a staff of 200, and has already launched four new collections. His most recent, at UNESCO, paid tribute to the variety of the human race.
