In the piece 'Artificial Life Metropolis CELL I would like to present three-dimensional plastic art as represented by a computer image using the basic principle of a cellular model as seen from an artistic point of view. The self-organization of a three-dimensional space, which is composed of a mass of 'voxel', can generate complex evolving space. This idea is inspired by the theory of self-organizing automaton in two-dimensional space. A model based on a three-dimensional cell model is capable of inducing unpredictable, delicate and emergent vibration using one simple rule.

We use grid coordinates to simulate the life and death of a cell in three-dimensional space. We also use the term of 'voxel' as an elemental cube in the grid coordinates. A group of 'voxel' make up a three-dimensional object, just as millions of cells make up a natural life form. The success of the self-organizing system of the voxel is correlative to the animation of plastic art, which is the object of experimentation within the context of voxel space.» (Yoichiro Kawaguchi)
