All of the images included in the film are interesting in their own way. Some may be colourful and grab the attention of the viewer in a good way, like watching the city at night, the dark colours contrast with the lights of the streets or cars. However, some may be colourful yet be shocking for the viewer to watch, for example, the rocket blowing up, the colours of the flames contrasting against the blue sky. The majority of the pictures around the cities and towns are sped up, this may be because it fits with the music that had been placed with it.
From having watched the Koyaanisqatsi film, it seems that there is no obvious concept or controlling idea. To me it just seems like a couple of cleverly shot pictures have been cunningly mixed or placed together with some influential music to make the viewers judge and evaluate the images and the music to come to their own conclusion.
