Ours is an uncertain world and stochastic art is hardly more effective than a coin toss.
Chance is considered the exotic factor in art.
"Randomness, chance, was also a very New York aesthetic strategy in the post-war years, but, in the wake of surrealism, it was also prominent in the approach of the American Painter Ellsworth Kelly"
Randomness and chance being in two places at once. The electron does anything it likes... It just goes in any direction at any speed, forward or backward in time, however it likes.
Stochastic art is but a lottery. Life drawing is a prototypic stochastic system, in which accumulations of random thoughts and ideas are associated with differential frequencies of failures, and visitor response. Fat chance for the minimal statistical model.
