The artwork generating system of escher-like positive and negative pattern evolution

Inspired by the composition characteristics of Escher's images, we noticed that regular mosaic patterns can be interconverted from background to foreground smoothly by gradually changing borders of mosaic shapes in a non-linear way. Based on this, we developed an interactive system to assist children in creating artworks of pattern evolution. In this paper, taking the child's graffti patterns as a source of inspiration, our system employed interactive GA (IGAs) to achieve the transformation and evolution of patterns as well as the positive and negative conjunction among any two or more patterns. Our developed system aims to not only help children complete the art creations for the transformation and conjunction of innovative positive and negative forms among patterns, but also inspire the development of their brain which is the original purpose of building the system.
