Apparency Half a century ago, Stern discussed this attribute of an artistic object and called it apparency. While art is not limited to this single end, he felt that one of its two basic functions was "to create images which by clarity and harmony of form fulfill the need for vividly comprehensible appearance." In his mind, this was an essential first step toward the expression of inner meaning. Kevin Lynch, The Image of the City artmeaningimagesharmonyform
Deep Interlock Forms which have a high degree of life tend to contain some type of interlock – a “hooking into” their surroundings – or an ambiguity between element and context, either case creating a zone belonging to both the form and to its surroundings, making it difficult to disentangle the two. The interlock, or ambiguity, strengthens the centers on either side, which are intensified by the new center formed between the two.
