# gst: monkeyflower Mimulus code, with a simple spot generator inside

<< Many organisms exhibit visually striking spotted or striped pigmentation patterns. Developmental models predict that such spatial patterns can form when a local autocatalytic feedback loop and a long-range inhibitory feedback loop interact. At its simplest, this self-organizing network only requires one self-activating activator that also activates a repressor, which inhibits the activator and diffuses to neighboring cells. >>

<< Patterns are everywhere in nature, not just color patterns but even how leaves are arranged on a stem, really anything with periodicity. Explaining these patterns could be similar in principle and that is what we're hoping to do, >> Yaowu Yuan
