Click the green flag to get each time a different Moiré pattern, generated with some randomness for length, gutter space and width of the patterns. In mathematics, physics, and art, moiré patterns are large-scale interference patterns that can be produced when an opaque ruled pattern with transparent gaps is overlaid on another similar pattern (source: https://en.wikipedia.org/wiki/Moir%C3%A9_pattern)
Another iteration assignment from the book "Code as Creative Medium" by Golan Levin and Tega Brain. I would like to add some interactivity, giving the user the opportunity to play with the space between lines, colors or orientation. Since I've used pen blocks I think I would need to refactor the code using clones. Maybe in the future :)
