Give it a try!\n\n## Threading\n\nThe reaction diffusion process runs better in a multi-core CPU, as the process is parallelized.  If you have a single core CPU, you may want to reduce the number of iterations per frame to improve responsiveness.\n\nIf the app is not responding well, try this:  locate `gui.OutputPanel.paintComponent()`\nand change\n\n```java\nfor(int i=0;i\u003c10;++i) {\n    model.performReactionDiffusion();\n}\n```\nby replacing 10 with a smaller number.  The animation is running 10 iterations per frame, and a lower number will slow\nthe process down, but it will be more responsive.\n\n## Colors\n\nAll the color choices are made in `View.updateImage()`.  Try replacing `rainbow()` with something else.\n\n## See also\n\nhttps://www.karlsims.com/rd.html\nhttps://github.com/jasonwebb/morphogenesis-resources#reaction-diffusion","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmarginallyclever%2Freactiondiffusion","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmarginallyclever%2Freactiondiffusion","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmarginallyclever%2Freactiondiffusion/lists"}
