#41.3 Fuji is a work-in-progress and part of an investigation into how the cooperation strategies of ants can be used to make images. Many people have drawn the parallel between the self-organization of neurons in our brain and the self-organization of ants in a colony. Also this kind of self-organization suggests other forms of political organization than the hierarchical ones we see today. A recent theme in my work is to build systems where images are produced by colonies of artificial agents, similar to ants, that live and cooperate in an artificial world, be it either in software or in hardware. These virtual ants live within the image, as it were, and their collective behaviour is their reaction to this image-environment. For #41.3 Fuji the ants live in time-lapse recordings of Mount Fuji, taken over a period of several weeks.
