Fibonacci Spiral It may be slow at the start because it is moving 0.001 pixels. Press space to hide variables. Use turbo mode for instantaneous drawing. (Hold shift and press green flag.) I recommend not doing it so you can see how the numbers go up. Fibonacci Sequence (First 20): 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181 Remember, this goes or forever. That was just the first 20.
I tried making a Fibonacci spiral a few months ago. It didn't work. I tried again and made it work.
