What happens when a flow field moves through some polygons scattered on the canvas?
Three variables, noise scale, step size and the alpha value of the particles moving through the flow field determine the kind of output you see.
In some cases, polygons stand their ground and are clearly visible but in some cases the field moves so fast that you can't even make the outline of the shapes.
