Here’s my submission😍
I created an interactive hero section for a skincare brand called “Baresol.” The background visually represents the texture, thickness, and colour of different skincare products, dynamically adapting to each one.
The hero section is powered by a fully interactive WebGL shader. As you move your mouse, the surface responds in real time—distorting into smooth 3D waves and swirls that mimic the natural flow and feel of skincare creams.
To enhance interactivity, I’ve added a controller in the bottom-left corner that lets users adjust:
Texture thickness Color saturation Flow intensity
There’s also a “Discover Our Products” call-to-action that smoothly navigates users to the product section.

The WebGL shader reacting to mouse movement is so satisfying — love how the texture controls let you feel the product
