It's interesting that a parallel development in science led to a similar discovery. In the September 1965, Scientific American magazine published previously unknown geometric configurations called the supercircle and superelipse which Piet Hein, a Danish mathematician, writer and inventor, arrived at through mathematical computation and computer research. More than a year earlier, unaware of Heins' calculations and working in almost complete obscurity in McLean, Virginia, Colin developed an almost identical configuration. Although Colin arrived at his supercircle through a visual and intuitive process, he did so with incredible mathematical precision. In spite of the fact that Colin's forms were hand-cut, there was no more variance than .004 of an inch of Hein's formulation.
"...It is just possible that Greenly in 1964 was the first person in the world to discover the supercircle's beauty and fascination... A year after Greenly made his drawing the Danish Mathematician Piet Hein published a supercircle configuration..."
