In this tutorial you will learn how to influence particles to rotate around a sphere using a force field and then act on gravity to make them fall back down. Originally the idea was to use boid-like particles with a goal and object avoidance but I came back to something simpler that didn't easily manage to use boids with gravity and ground collision. I hope you will find this tutorial useful in your future projects.
