Shall I call it algorithmic sketching? May be.
It's for some drawings on Ipad with a not so famous app which I really can't remember it. It was done few years ago using my finger, no stylus used. However, I love the effect of such lines connected together based on how long and how fast I stay on a particular point and its distance from surrounding points. It's great anyway and I love the algorithms behind it.
