Although the video artwork Evolution cites the well-known image of hominid evolution, it is more interested in the evolution of the media than in the evolution of the human species. Through the feedback of a system of video devices and the search for image imitation, it creates a layered (self-)reflection of the media used. It illustrates the gradual peeling back of artistic and technical possibilities in sound, from which an image is generated by directly manipulating the surface of the filmstrip, and in images that generate sound in video feedback.
