Quanta are the smallest discrete packets involved in any physical interaction. This means that in any collision involving a horse, boy and a duck the quantum, or smallest unit of measurement, will be described by the duck, which is likely to get the worst of such a collision and give up its energy to alter the energy states of the other incident entities. Perhaps the horse is unfazed but the boy consumes the duck. Being thus invigorated the boy saddles the horse and rides away an entirely new, more complex entity composed of all three but given power and being through the sacrifice of the duck. As I have no access to a particle accelerator, I must make do with my thought experiments, and Koi Quanta is one such experiment. Usually, my Simplexity paintings are composed of lens shapes formed freehand with a loaded brush, but fitting the experimental approach of this Tondo I made a series of quantified stencils from transparent plastic. Pencil outlines are visible through the transparent layers of paint which build to create the surface of this work. I used 4 stencils of similar shape but sized in discrete quanta; the smallest being 2/3 the size of the next smallest, the next increasing another 1/3, etc. The lenses are arranged in strings and clusters, the nexus of which represents collisions. The restricted palette clarifies the results of this painterly experiment in tone and mass built around clustered lenses. When I was finished, it was the resemblance to golden fish like Koi in a feeding frenzy which moved me to name this Tondo Koi Quanta.
