PatterNodes 3.1.4 | macOS | 17 mb PatterNodes is a tool for creating graphical patterns, animations, gradients, or illustrations based on repetitions. This is done by defining a sequence of steps, a recipe of sorts, that describes the pattern. Each pattern element or operation is represented by a little panel called a node, and the nodes are then linked by connections drawn between them. As the nodes can be freely combined and connected, this gives you a very flexible and powerful interface.
