A Geometry Nodes setup for simulating particles moving along curves. Built using a simulation zone, the tool animates dynamic particle flow with user controls for motion, density, and instancing. Parameters allow adjustments to simulation speed, positional noise, and oscillatory wiggle for varying trajectory movement.

Users can refine the start and end radii to control how particles spread at the ends of the curve. The node group supports custom object instancing, offering random rotation and minimum/maximum scale limits. Additional features include density masking and material assignment, along with a custom points_factor attribute output designed to drive gradient ramp shading across the particles.
