Two spirals in different colors, mirroring each other from the center.
📖
How this works
Two spirals sharing a center. The first goes right, the second goes left — mirroring each other. Between them, turtle.home() jumps back to the middle without drawing (thanks to penup).
Your turn — try these
- 1Add a THIRD spiral in green with `right(89)` instead of 61.
- 2Change one of the spirals to grow with `i * 3` instead of `i * 2`.
- 3Loop through a list of colors so each rotation changes color.
