Nature has become the resource to keep this artificial or new nature alive. Koyaanisqatsi is not so much about something, nor does it have a specific meaning or value. Koyaanisqatsi is, after all, an animated object, an object in moving time, the meaning of which is up to the viewer. Art has no intrinsic meaning. This is its power, its mystery, and hence, its attraction.
Art is free.
It stimulates the viewer to insert their own meaning, their own value. So while I might have this or that intention in creating this film, I realize fully that any meaning or value Koyaanisqatsi might have comes exclusively from the beholder. The film's role is to provoke, to raise questions that only the audience can answer. This is the highest value of any work of art, not predetermined meaning, but meaning gleaned from the experience of the encounter. The encounter is my interest, not the meaning.
