Decided - out of personal curiosity - to explore trying to create shapes produced by varying length rotating vectors.
Motivated by looking at a leaf and wondering: Could its outline be reproduced by the tip of a varying length rotating vector ?
(My maths ability is basic/general level. So apologies for inaccuracies, bad calculations, which I tried hard to avoid.)
