Web developer and tech artist Faraz Shaikh showed a liquid glass effect he created using the Three.js JavaScript 3D library.
The drop-like shapes move smoothly thanks to MeshPhysicalMaterial with a fully ray-marched surface made of Signed Distance Fields (SDFs). You can enjoy the visuals in Shaikh's demo and see the code on GitHub.
Shaikh has other fascinating projects on his X/Twitter, check them out:
