This is part of a series of algorithmically generated posters based on statistical information provided by Last.fm software. Every song listened to by a particular user over an eighteen month period of time is recorded and used to create the visualization. Each colored band represents a musical artist, progressing left to right through the eighteen month span growing wider when listening was more frequent, and skinnier when it was not. The hue of the artist represents the time of the first listen for the particular user: cooler colors represent artists who have been listened to for a long period of time while warmer colors represent artists who are more recent in the user's listening habits.
The resulting poster is printed at 11" tall by up to 75", each month is represented by 3.75". While these are visually interesting, they tend to have a much stronger effect on a personal level since the user draws connections between unique patterns in the poster and correlating events in their life.
