Press: A to change some spike lengths B to change others M to add rotation symmetry o spikes 1 to smooth 2 to form A spikes 3 to form B spikeks Z to see an animation (can change A, B, M and 1 during animation) X to experiment with A and B (can change M, 1, 2 and 3 during X) C to experiment with 2 and 3 (can change A, B, M and 1 during C) V to experiment with 1 (can change A, B ,M, 2 and 3 during V) Press green flag after messing around with Z, X, C or V to do another experiment or animation. VVVVVVVV Mainly works with small numbers.
This is a thing you might have heard of with No Man's Sky: a game I wish I could get. It is a formula that requires 6 values; a, b, m, n1, n2, n3. These control and create shapes that appear in nature and uses polar coordinates (r, theta). Scratch mainly uses Cartisian coordinates (x, y) so I had to convert between them. See the wiki page for cool patterns.
