Diamond Twirl Composition was inspired by a series of OP Art paintings done by Victor Vasarely, called Collage Vert (c. 1990). Vasarely died in 1997 in the early days of computer art. I'm sure he would have embraced this medium. This is the second in a series of Vasarely inspired Generative Art pieces I am offering. I became interested in Victor Vasarely's graphic artworks while I was in art school. As I struggled to learn computer graphics I wondered how do I write a program to produce imagery with a similar aesthetic? I call the process of creating algorithms inspired by other artists: "Art"ificial Intelligence. Diamond Twirl Composition is a regular grid of square tiles. The background of each square tile is filled with a random color. A coin-toss algorithm then decides whether to draw a diamond shaped polygon in its own random color leaning left or leaning right connected to opposite corner of the square tile background. Every iteration is unique and filled with energy. Dr. Bill Generative Art OG @ drbillkolomyjec.com
