@txo_elurmaluta It's a maze where the paths have a bias to follow a polar graph of a multi-armed spiral. The animation colors each segment of the maze based on its distance to the starting point with a shifting phase.
@tschundler Right. Their behavior is only coherent because the underlying noise function is coherent. I just add a looping noise value to their start position and scale it back down into a sphere.
This is basically the same code as my flocking algorithms, but looks cooler. 12,000 particles "flock" to be near their loop neighbors while avoiding other collisions.
