I wrote the original code for this work as a daily coding sketch in September 2022, "220916a".
"10 PRINT CHR$(205.5+RND(1)); : GOTO 10", the rich algorithm created by crossing two different diagonals, is always a favorite in my toolbox of fresh insights.
On that day, I sketched an image in code of a snail crawling along the diagonal lines, twisting and turning. This time, I wrote the code with the idea of a snail waddling around the perimeter, waiting for the rainbow. Yes, the snail is my alter ego who writes code slowly.
