I replaced the spirals with my own special method for drawing interesting patterns, and added support for drawing multiple patterns at once through the use of clones. Click to draw a pattern. (patterns are randomized) About 1 in 8 patterns will result in a long line. Hold the mouse and spacebar to draw many patterns at once.
Made for the Scratch Design Studio "Remix a Starter Project" using the patterns from my own project "Numbered Pattern Drawer".(https://scratch.mit.edu/projects/198064620/)
