To make sense of the swirling mass of points, let’s break it down into pieces. Here is the same animation shown for points that start off inside the main cardioid. Points in this section don’t oscillate, so everything is nicely calm and soothing. https://www.youtube.com/watch?v=6sVF5uA1gLQ

Points in the circle to the left of the main cardioid fall into period-2 orbits. https://www.youtube.com/watch?v=0pbosYwMYLo

Points in the circle above the main cardioid fall into period-3 orbits. (To explore more orbits, drag your mouse in Stefan Bion’s orbits explorer here: http://www.stefanbion.de/fraktal-generator/z-orbits.htm ) https://www.youtube.com/watch?v=8akHER-UO5w

And starting with the points outside the Mandelbrot set we get this. All of these points eventually diverge and disappear. The average of the integer frames gives the amazing Buddhabrot, discovered by Melinda Green (@cutelyaware): https://en.wikipedia.org/wiki/Buddhabrot https://www.youtube.com/watch?v=icUWpJ6LA3I

I’d given up on The Expanse because it was just soap opera set in space but Series 2 is realy excellent.

This is my favourite video of the recent SN8 test flight, starting at 6:05. You see the implausibility of the rocket falling sideways through its own launch cloud, and then not flipping until it almost hits the ground. And the reactions of the crowd! https://youtu.be/amFK58SSphY?t=365
As brexiters are finally being brought in conflict with hard reality, I wonder if there’s an inkling of a thought in their minds that maybe, just possibly, brexit is not a good idea?

We had duck. Just me and our child, because my wife is vegetarian. A 2kg duck only feeds 2, to the cats’ disappointment.

Are you getting the geckos to breed?
Sea of Simulation, from the TRON: Legacy soundtrack is very relaxing. You can feel the waves washing in and out. And in the spectrogram below you can see their rise and fall very clearly. https://www.youtube.com/watch?v=_bz8rU7LdyE
Replying to @zzznah
If you start with a white background and one green blob, do you just get one very long gecko? If so then self-reproduction is very close: add subtractive noise to break the long geckos apart, and they will self-repair. Or maybe the NN will learn to do this with the right loss fn.
