This research used stigmergy behaviour, another example of agency-based systems, which could be programmed to be highly adaptive to local data. What is most intriguing and attractive in this case, is contrasting organic aesthetics emerging from algorithms like stigmergy, with its plant like formations, and the hyper-rationalisation and genericity of voxelised geometry. Different resolutions were introduced in the facade panels, by using an octree algorithm. The result is a building skin that from afar looks like a plant, but in close up has almost Minecraft-like aesthetics coming from a multi-resolution voxel field. Organic stigmergy (stígma + ergon) partly plays a role in the distribution of data through the facade field, rather than generating geometry. It leaves its imprint in the density of geometry
