</html>About this animation
Fast-moving corridor effect resembling hyperspace.
Under the hood
3D Z-Axis Scaling
Elements are spawned in the center of the screen with a scale of 0. They are then animated outwards toward the edges while exponentially increasing their
scale and opacity. This mimics the classic 'warp speed' aesthetic popularized by sci-fi media.
