What’s the Plan?
We’ll create an animation where an image is revealed through a circle that moves with your mouse. You’ll also be able to tweak the size of the circle and experiment with the behavior.
Here’s what you’ll need:
GSAP: For buttery-smooth animations.
Tweakpane: For a slick UI to adjust the animation on the fly.
HTML & CSS: To set up and style the page.

img {

clip-path: circle(var(--size, 10%) at var(--x, 50%) var(--y, 50%));
transition: clip-path 0.6s;
}
JS
import gsap from "https://esm.sh/gsap";
// Smooth animations
const xTo = gsap.quickTo("img", "--x", { duration: 0.6, ease: "power3" });
const yTo = gsap.quickTo("img", "--y", { duration: 0.6, ease: "power3" });
const sizeTo = gsap.quickTo("img", "--size", { duration: 0.6, ease: "power3" });
// Update based on mouse movement
window.addEventListener("mousemove", (e) => {
xTo((e.clientX / window.innerWidth) * 100);
yTo((e.clientY / window.innerHeight) * 100);
});
