I mean Parallax Scrolling which is a technique often used in good ol’ arcade and video games like Moon Patrol or Sonic the Hedgehog. In such 2D games parallax scrolling was used to create an illusion of three dimensional depth.

Moving Sonic the Hedgehog to the right caused the foreground to move past the camera to the left faster than the background, creating a faux-3D view of Green Hill Zone. We can create a similar effect on a web page by fixing semi-transparent background images to different sides of the browser viewport, and at different horizontal percentage positions.
