Check out Ten Thousand Cents, a Mechanical Turk project. Each participant was paid a penny to draw one section of a hundred dollar bill. Ten thousand of these images, at one cent apiece, make up $100 (clever). U.S. users spent just under 3 minutes, on average, creating their little slice. That’s less than $0.20/hour for those keeping score at home.
Of course, this is a fun and interesting experiment, but still… How much is your time worth?
