Patternodes is a tool for creating graphical vector patterns, animations or illustrations. This is done using a node-based interface where you define a sequence of connected nodes that describe the design, each representing graphical elements, changes or repetitions. You might call this a sort of parametric design or visual scripting for 2d applications.
The node sequence is completely non-destructive, so you can change any step in the sequence at any time without having to redo the rest. The parameters that control each node can also be connected to other nodes, establishing complex relationships, or animated to create animations.
Patternodes is designed from the start to stimulate playful use and experimentation. Therefore the result is always shown in the preview view, repeated for patterns and updating in real time.
Earlier versions of Patternodes 2, compatible with macOS 10.10 can be found here.
There is a collection of projects that could work as inspiration for what you could use Patternodes for here on Behance:
