that’s a lot of knots for such a simple shape !

that’s cool… but as for all random generators the most complicated thing is to make it predictable. that means give to user a chance to make what he wants

try to make it keeps a shape when changing a number of steps… the idea is:

i like the generated shapes, but they are too heavy. let me try to make the same but with less number of knots

i really like your simple and vivid algorithm. i’m just suggesting you to make a tool, not a toy.
look at the seed method

Denis is right, plant some seeds up in that MF,
