Evolution of a line

"A Sequence of Lines Consecutively Traced by Five Hundred Individuals is an online drawing tool that lets users do just one thing - trace a line. Each new user only sees the latest line drawn, and can therefore only trace this latest imperfect copy. As the line is reproduced over and over, it changes and evolves - kinks, trembling motions and errors are exaggerated through the process. A Sequence of Lines Consecutively Traced by Five Hundred Individuals was first created as a tool to be used in conjunction with Amazon’s Mechanical Turk - an online labor market. Mechanical Turk workers were paid 2 cents to trace a line."
