Particle Flow Field
Particles drift through a mutable force field that bends under your mouse.
Open fullscreenAbout this sketch
This sketch visualizes a grid of force vectors that steer small particles across the canvas. Moving the mouse injects directional energy into the nearest cell, while left-dragging pulls a wider patch of the field into motion. Right-click to spawn more particles and watch their red trails reveal the changing flow.
