Jean-Paul Riopelle to abstract expressionism), in which he used myriad tumultuous cubes and triangles of multicolored elements, facetted with a palette knife, spatula, or trowel, on often large canvases to create powerful atmospheres. The presence of long filaments of paint in his painting from 1948 through the early 1950s has often been seen as resulting from a dripping technique like that of Jackson Pollock. Rather, the creation of such effects came from the act of throwing, with a palette knife or brush, large quantities of paint onto the stretched canvas (positioned vertically). Riopelle's voluminous impasto became just as important as color. His
Fractal expressionism paint onto the canvas. Taylor points to two aspects of Pollock's painting process that have the potential to introduce fractal patterns. The first is Pollock's motion as he moved around the canvas, which Taylor hypothesized followed a Levy flight, a type of chaotic motion that is known to leave behind a fractal pattern. More specifically, a number of studies have shown that the motions associated with human balance have fractal characteristics. The second source of chaos could be introduced through Pollock's pouring technique. Falling fluid has the capability of changing from a non-chaotic to a chaotic flow, meaning that Pollock
