A dedicated website was created for "Exhibit 13", and contains a (lower resolution) copy of the video composed for the song, made up of drifting images of collected, scorched pieces of paper. Checked the website January 31st, 2014. It does not appear to be still active.
The last 4:19 of the song is a hidden track, Mandelbrot No.4. This makes Exhibit 13's length actually 8:50, with a 30 second pause between the two tracks.
