I had originaly created the graphic to demonstrate Gestalt (http://chd.gse.gmu.edu/immersion/knowledgebase/strategies/cognitivism/gestalt/gestalt.htm), the German word for "form," (in a word, sprechen ze deutch) and as it applied in gestalt psychology it means "unified whole" or " configuration."
Ge·stalt ( P ) Pronunciation Key (g-shtält)
A physical, biological, psychological, or symbolic configuration or pattern of elements so unified as a whole that its properties cannot be derived from a simple summation of its parts.
I had said that if you answer the question of why it looks like a shamrock you would have your answer. Gestalt theory explains in part how humans are able to percieve objects composed of unconected and disparate items or elements.
In any event, human capability of pattern recognition is quite beyond our current understanding and far beyond any computer's ability (at least at this time).
Gestalt theory first arose in 1890 as a reaction to the prevalent psychological theory of the time - atomism. Atomism examined parts of things with the idea that these parts could then be put back together to make wholes. Atomists believed the nature of things to be absolute and not dependent on context. Gestalt theorists, on the other hand, were intrigued by the way our mind perceives wholes out of incomplete elements [1, 2]. "To the Gestaltists, things are affected by where they are and by what surrounds them...so that things are better described as "more than the sum of their parts."" [1, p. 49]. Gestaltists believed that context was very important in perception. An essay by Christian von Ehrenfels discussed this belief using a musical example. Take a 12 note melody. Play it in one key, say the key of C. Now change to another key, say the key of A flat. There might not be any notes the same in the two songs, yet a person listening to it knows that it is the same tune. It is the relationships between the notes that give us the tune, the whole, not which notes make up the tune.Principles:
