Jonathan McCabe - generative art
Reaction-diffusion / Turing patterns
My art is indirect. I’m using a computer to translate the text I write into an image or animation. The text describes a process that leads from randomness to order, a self-organising system. The process is based on a theory of pattern formation in nature. It is certainly in the “generative art” practice. I’m using two pattern-forming processes at the moment. One is calledreaction-diffusion or Turing patterns. Alan Turing, the English mathematician who made fundamental contributions to the theory of computation and helped break codes in World War Two, wrote a paper in 1952 called The Chemical Basis of Morphogenesis where he described a process that could plausibly generate some of the patterns and structures apparent in living creatures. This process spontaneously produces stripes or dots from an initially random state. I’m making more complicated patterns by adding together Turing pattern processes at different scales, which fight with each other over what state each pixel should be in. The other pattern-forming process is loosely based on natural processes is a simulation of compressible fluid flow in 2D. This process added to the previously described process gives quite interesting effects, like marbling. Generative art can be very frustrating, as there is not much control over the product, only an opportunity to change the generative process. I have found this working for clients, when they ask, “can you change this particular thing?” when I don’t know how that particular feature arose. Generative art can be very productive, spewing out many related versions of an art piece in a way that is against the idea of a unique and special image, a kind of anti-art.

Pendulum
With gravity as the acting force, these plates are decorated by a pendulum. The patterns are a graphic representation of the oscillation of a pendulum, revealing a hidden pattern that exist in nature. The result is a play between the mathematical rules of the natural oscillation and the randomness of the human that initiates the swing of the pendulum.
