Tundra
Tundra by Miroljub is a one stop grasshopper plugin for generating complex noise patterns. Includes noise generators as well as lots of useful methods such as filters, modifiers, combiners, transformations.
Benvis Gradient Venation
In this grasshopper definition by creating a particle simulation with Stella3d Plugin, and allowing particles to follow in a field generated by the Tundra Plugin, you can create a parametric particle-based motion.
Kinetic Wall
In this grasshopper definition by creating and adjusting a parametric noise on a grid of points and then lofting them back you can model a kinetic like form.
