natural systems constantly produce an endless number of effects. Visual, sonic, theatrical and many other. But these effects are mearly a by product. A side effect of coherent, organic systems or structures. They are obviously not the cause, nor the aim. 

art making, in any field, is a constant choice between trying to produce premeditated effect, or concentrating of devising a coherent system that will In its turn, generate all sort of effects. 


The first is lazy and opportunistic and is a sort of reverse engineering, the second is what art making is all about.
