This project generates Optical Art with two colors by utilizing randomly generated circles and lines that overlap. No two bordering regions have the same color. The complexity parameter (revealed and hidden by up/down arrows) ranges from 1 to 20 and determines the number of overlapping circles and line. Turbo mode may help. For a quick rendering try a small complexity. Each run of the green flag a new random art will be generated. For fast rendering: http://phosphorus.github.io/#80134872
The inspiration is works of Hungarian Op Artist Victor Vasarely.
