Normally with the Latona process, patterns are not created in a stop frame manner. Instead, structures are created, parameter ranges defined and then values are randomly chosen to create the pattern. The Pollack example above could have been completed an infinite number of ways. What you see is only one possibility.
This can potentially add interest to the audience since they could see a work several times and not see the same pattern. The art does not have to be static. It can change with every showing. The art is in the choices in elements and limits defined by the artist, not in the execution.
