Nice one Peter - again, it's graphics that make it powerful. So much in the visual world is dependent on blocks and weights!
In that Bert Stern video he talked about being indoctrinated with the idea of the triange forming a strong base function... I really wonder if some parts of theoretical art instruction don't create as many problems as they solve; I can't rmember ever being taught anything about the golden mean, rule of thirds, or any such stuff: wasn't given the chance at the stage in life where I wanted it. Yet, I can't say that I was ever prevented from making the relevant subconscious decisions in a manner that might have followed had I had the formal eduction in the subject to make them conscious decisions: it comes down to gut.
Come to think of it, the more one delves in to these things the greater the fear of self-induced paralysis! Much like sex, then: doing what comes naturally. Or eating.
