Sum Ergo Demonstro Explained

This is a video presentation of some of the techniques used in my demo Sum Ergo Demonstro for the Raspberry Pi Pico 2 board, with its RP2350 microcontroller. Some new discoveries are revealed.

You can watch the demo here.

My earlier demo for the same microcontroller, Kaleidoscopico, is embedded on this page, which also contains an extensive technical writeup.

More resources mentioned in the video: The Fractal Flame paper by Draves et al., and the excellent RP2350 datasheet.

The fractal effect is really cool, I was quite puzzled by the symmetry. My guess was that you drew each point of the attractor three times, once as is and rotated by 60 and 120 degrees, but I couldn't figure out why the symmetry is not quite perfect. The flame algorithm explains it all, quite an elegant approach.

Great demo and deep dive as always!
