I have finished my Mandelbrot program. I’ll let the README on GitHub explain what the program does and, how to use it.

I would like to note a couple of PicoCalc folks that made this possible. First would be @BlairLeduc for the picocalc-text-starter. Without this foundation I could never have written my program. Second would be @pelrun for uf2-loader. I would have given up if I had to find the bootsel button and plug in the USB cable for every code change. Thank you both.
Hopefully there’s a few other folks who are as fascinated by Mandelbrot as I am and will enjoy exploring the set.
