In this grasshopper definition you can generate a bracelet by creating a curve based on a differential growth algorithm by using the stella plugin.

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.

In this Grasshopper definition by extracting vertices from a spherical mesh and using the Stella3d plugin to generate forces, you can deform the mesh till the vertices reach a minimum distance.

In this grasshopper definition by using the Stella3d plugin and Weaverbird you can model a parametric expanding voronoi cell model.

In this grasshopper definition you can model a constantly changing surface by using the Stella3d Plugin, and defining an attractor which attracts the particles towards itself.

In this grasshopper definition you can simulate a series of particles moving around a curve and making a bridge like structure.

In this grasshopper definition by creating a simulation with Stella3d you can simulate particles with attractors and use the Metaball(t) component to convert them into metaballs.

In this grasshopper definition by using the Stella3d plugin you can simulate a series of particles which try to reach defined point targets and then voxelize them by using Cocoon, you can also refine it as an additional step.

In this grasshopper definition by using Stella3d for particles simulation ,you can move a series of geometries around a defined NURBS curves while they get bigger as they move forward.
