If you're a fan of optical illusions, you'll appreciate a new campaign from Etrade that uses them to "lend a new perspective" to the world of trading.

The spots, by R/GA and production company Brand New School, were shot in a single take and change the angle and position of the camera to reveal another picture: for example, in one, seen here, a man's face changes into a customized Etrade interface, while in another, a computer screen becomes a trading floor. They conclude with the tagline. "It's your trade. Etrade."

Both spots are set to music composed by Tom Rowlands of the Chemical Brothers. Brand New School and director Jonathan Notaro shot them in a a 10,000 square foot warehouse and used 1553 feet of lumber, 87 gallons of paint and 217 hand-made props.
