Hi new followers!  Thanks for enjoying my work.

Today’s gif on radar was an example of Turing Patterns aka a Reaction-Diffusion system.  My version is based on a image-processing trick I picked up a while ago.  If you have Photoshop or similar you can do this without any code!

  1. Take an image, preferably B&W
  2. Blur
  3. Sharpen
  4. Repeat Steps 2-3 to taste

You might need to adjust the blur/sharpen amounts.

If you are using code, I have an example in Processing that demonstrates it as well.
