Spacetime Grid: an interactive 3D cursor template
A neon grid that sags into a gravity well under the cursor, with marbles orbiting into it.
Try it: Move the mass · click to drop a marble. Open the live Spacetime Grid full screen.

Physics, space and science content, gravity-themed launches and dark tech heroes.
How it is built
A line grid is warped in the vertex shader by a gravity well under the cursor, and marbles orbit the well using the same depth function on the CPU. 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 Spacetime Grid 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.
