Clement Valla asked 500 Amazon’s Mechanical Turk users to trace a line. The first user started with a straight line, the next user had to trace the previous user’s trace. I guess it’s no surprise that the last trace doesn’t remind you about the initial straight line. The result is “A Sequence of Lines Consecutively Traced by Five Hundred Individuals”. The cool thing about this is the fact that Clement only payed $0.02 for every trace, so it has only cost him $10.
You can still participate in Clement’s current project “Copy Images using a simple drawing tool“, you’ll get $0,04 per drawing.
