A perspective on artistic creativity developed by an artist and a psychologist is presented. The artist approaches art as a semiotic system built upon relations between visual isomorphisms. The psychologist is concerned with the origins of analogical thought in children's symbolic play and its possible maturation into a component of adult creativity. The paper is divided into two parts. In the first part the artist presents his aesthetic rationale and outlines the creative process. The focus is on the role of isomorphisms in visual art, both historically and in the artist's own work. In the second part of the paper, the psychologist discusses the artistic manipulation of isomorphisms as a theoretical construct in psychology. The concept of isomorphisms is placed into a larger theoretical perspective that studies creativity as a maturation of children's symbolic play. It is suggested that the ability to perceive and manipulate isomorphisms originates in children's symbolic play and matures into an important component of adult creativity. Preliminary findings of an instrument designed to measure creativity and aspects of symbolic play are presented. (RM)
