My instructions were
Draw two equal length lines perpendicular to each other where the midpoint of both lines are shared. Connect the endpoints to make a square. Pick a number from 5 to 10; we’ll now call that N. Draw N points on the edges of the square, so that there is at least one point on each edge. While any point has less than 2 connected lines where the square’s edges are not counted, draw a line from one point to another of the N points. Shade in 3 non-adjacent areas which aren’t crossed by a line in the figure. Sign your name.
I had planned for shapes that more resembled stars when I created my instructions. In retrospect I should have made more constraining rules.
