A cousin of mine shared this on my Facebook last week and I think this is such a supergreat initiative by Nike for their fans...
Plus I would definitely want one to be hanged up in my room if I ever have the chance to create this artwork... :)

For the launch of the Nike Free Run+ 2 City Pack series, YesYesNo was invited to develop software that would allow runners to create dynamic paintings with their feet using their Nike+ GPS run data. During the two day workshop at Nike headquarters, we invited the participants to record their runs and then using our custom software we imported the metrics from their run, to create visuals based on the speed, consistency and unique style of each person's run.
