HTML

<div class="wrapper">
    <div class="card">
        <div class="me">
            <div class="eye"></div>
        </div>
    </div>
    <div class="text">Hi~</div>
</div>

JAVASCRIPT

와 굉장히 어렵네요? 개발자 거듭나기님께 물어보시죠...

const wrap = document.querySelector('.wrapper');
const eye = document.querySelector('.eye');
const speed = 1;

let x = 0;
let y = 0;
let followX = 0;
let followY = 0;

    x += (followX - x) * speed;
    y += (followY - y) * speed;
    
    eye.style.transform = `translate(${-x}px, ${-y}px)`;
    wrap.style.transform = `translate(-50%, -50%) perspective(600px) rotateX(${-y}deg) rotateY(${-x}deg)`;
    
    requestAnimationFrame(animate);
}

window.addEventListener("mousemove", (e) => {

    let mouseY = Math.max(-100, Math.min(100, window.innerHeight / 2 - e.clientY));
