Eyes follow mouse using javascript mousemove event

the "eyes follow mouse" effect is a popular visual interaction that creates a playful and engaging user experience on websites. using the javascript `mousemove` event, developers can track the position of the mouse cursor within the browser window. by capturing the mouse coordinates, they can dynamically adjust the position of graphical elements—often designed to resemble eyes—so that they appear to follow the cursor's movement.

this effect can be achieved by calculating the angle between the eyes and the mouse position, then adjusting the eye's gaze accordingly. it enhances interactivity and adds a layer of whimsy to a webpage, making it more immersive for users. additionally, this technique can be combined with css animations for smoother transitions, further enriching the visual appeal. overall, the "eyes follow mouse" effect demonstrates how simple javascript interactions can significantly enhance user engagement and enjoyment on a website.
