flickr flow

fernanda viégas' and martin watternberg's flickr flow:

"The two of us see the world as a stream of color, and in 2009 we finally had a chance to draw the river in our heads. We began with a collection of photographs of the Boston Common taken from Flickr. Using an algorithm developed for the WIRED Anniversary visualization, our software calculated the relative proportions of different colors seen in photos taken in each month of the year, and plotted them on a wheel. The image below is an early sketch from the piece. Summer is at the top, with time proceeding clockwise."
