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.
In this grasshopper definition by applying forces and noise, you can model a natural movement of particles. This definition is using Anemone and 4D Noise plugin.
In this definition you can make a fractal rotating polygon by using the Anemone plugin. First we are going to explode the curve to its segments and then evaluate a point on the edges. This recursive algorithm will produce the final rotating polygons.
