Firefly Swarm: an interactive 3D cursor template
Hundreds of blinking fireflies that follow the cursor over tall grass and scatter on click.
Try it: Lead the swarm · click to scatter it. Open the live Firefly Swarm full screen.
Where the Firefly Swarm works best
Nature, camping, evening events and calm, magical heroes.
How it is built
Hundreds of glowing points each orbit their own spot near the cursor with a lazy wander, blinking at individual rhythms; a click scatters them. The whole effect is plain three.js in one module script. It renders only while it is on screen and caps the pixel ratio on high-density displays to protect performance.
Add it to your website
- Add a Code, Embed or Custom HTML block where the effect should sit (Webflow, Framer, WordPress, GoHighLevel, Shopify or plain HTML).
- Paste the snippet. It is one element and one script; three.js loads from a CDN.
- Edit the colours and words in the settings block, then publish.
Frequently asked questions
Is the Firefly Swarm template free?
Anyone can open it live and try the interaction. Copying the code is included with a Scrollhaus plan.
Does it work on mobile?
Yes. On touch screens it runs a gentle automatic motion so the scene is never still, and taps trigger the click interaction.
Do I need Spline or three.js experience?
No. It is one HTML element and one module script. Colours, text and images live in a settings block at the top.

- Connection Globe: A dotted globe that fires glowing arcs from wherever the cursor lands, like data travelling around the world.
- DNA Helix Unzip: A rotating double helix whose base pairs unzip wherever the cursor passes along it.
- Hologram Projection: A flickering cyan hologram above a projector that turns with the cursor and glitches when touched.
- Particle Sphere Repel: Nine thousand glowing particles on a sphere that part around the cursor and burst outward on click.
- Hyperspace Tunnel: A neon ring tunnel with light streaks that bends toward the cursor; a click kicks it into warp speed.
