Impurity was uploaded on September 01, 2009. It is a video reply to Entry 12. Its description is "000000000". It is tagged with "marble", "hornets", & "ark". In total, the clip is 0:34 long. The video seems to be in four sections. In the first section, there is no audio track, and the only visual is a blinking "begin". In the second section, a series of zeroes is presented, where the main message seems to be: 00000000000000000000000000 00000 000000000000000000 000000000000000 In the third section, some tree tops are filmed in the rain during a thunder storm. The audio appears to be of that storm - including rain and thunder sounds - along with a frequency of 1046 Hz. Right before the cut to the fourth section, the word "operator" appears in the plant. In the fourth section, a heavily distorted audio clip is played and the screen is filled with zeroes. Among the zeroes are the letters "T H E R E W A S M R E."
