thanks! it's done in 2 different ways.
1st is by drawing each sprite 3 times with the aid of onion skinning, which let's you see the other sprite opaque while redrawing. (https://en.wikipedia.org/wiki/Onion_skinning)
2nd is with the use of a few scripts i made where multiple lines get drawn with an offset instead of one straight line. the offset is random with a seed based on a rounded of time variable, so the lines don't wobble too often.
