Cursor-Reactive Particle Field Screensaver
The Cursor-Reactive Particle Field screensaver shows a real particle field that genuinely responds to your live cursor position, even in fullscreen. It is free, runs in your browser, and ESC exits.
How the Cursor-Reactive Particle Field screensaver works
The saver tracks your real, live cursor position and steers a field of particles toward or around it.
Moving the pointer works in fullscreen too — only the ESC key exits, so you can genuinely play with the field without leaving.
If your cursor stays still for a while, the particles drift toward a slowly wandering point on their own, so it still looks alive when left unattended.
The whole scene runs as pure canvas math, with no external assets.
A worked example
Sweep your cursor across the screen and a real trailing swirl of particles chases it, exactly tracking your pointer's real path.
Settings & tips
- Accent recolours the particles.
