Turns out the Pale Blue Dot image was taken on february 14, back in 1990. Since I already posted it two weeks ago, I wasted my opportunity to post it the same day as everyone else!

What the heck, I'll repost the picture but spare you the quote. In case you're wondering, the little blue pixel is all of earth as seen from space

"Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives."
- Carl Sagan, Pale Blue Dot

Made a little pixel art solar system with planets roughly to scale.

Libresprite is a pretty neat little tool!

The theory behind is based on reaction-diffusion equations, if you want to go deeper into the technical stuff.

The pictures are borrowed from this scientific review article also by Philip Ball and has a comprehensive overview of the subject, showing how the theory ranges from waves i na petri dish to stribes on a zebrafish or ripples on a sand dune.

Great stuff!

If you ever wondered how spots and stribes on animals "know where to appear", I can highly recommend Phillip Ball's three-book series "Nature's Patterns: A Tapestry in Three Parts", particularly "Shapes"

Very accessible and illuminating on a complex topic.
