Use turbo mode, or don't... it's relaxing to watch it draw if you prefer the slow way (but also takes forever if you use a small step size). This project draws a different random maze in rainbow colors every time you press the green flag. Peek inside and change the "size" variable or the pen size variable for different results. You can also change the coloring algorithm if you don't like concentric rainbow circles. Sometimes funky things happen around the edges, and since i have no idea why that happens, I'm going to ignore it.
This is inspired by a page in "Patterns of the Universe" by Alex Bellos and Edmund Harriss, which is a coloring book for nerds like me. There are two different types of patterns to fill each square, and the program randomly selects between the two. If you look inside, each pattern is represented by a different custom block ('1' and '2').
