Abstract

This paper explores artificial collective artistic work inspired bynatural phenomena, namely the use of pheromone substances for mass recruitmentin ants. Our goal is to look for innovative patterns using techniques derivedfrom Artificial Life. We will play 2 variations, based on imitation, on asociety of anonymous and homogeneous artificial micro-painters (the Colombines).In the Colombines model the virtual canvas, besides being a computationalspace for depositing paint, is also a pheromone medium, mirroring thepainting patterns and influencing the painters' behaviour. More, the micropaintersdo not exchange information directly with each other, they are simplyattracted towards non-painting areas of the canvas--the non-painted "tableaux"patches diffuse an "environmental produced" chemical and the painters preferto follow the chemical gradient. Thus, this form of stigmergic communicationsimply influences the artistic agents movements. We will expand the Colombinesbasic model adding direct communication between the micro-artists: theywill imitate the colour of others. In the first variation, they will imitate the colourof who ever they interact with and in the second one they will have a forceattribute and colour imitation will depend on the force relationship betweenthem.
