In a demonstration hosted on codepen.io, CSS syntax is almost entirely responsible for an elaborate effect resembling an array of differently colored cubes that are arranged in a square. The arrangement rotates as though a camera were viewing it from an isometric perspective and circling around it, but the CSS code appears to be producing visuals simulating this effect without employing any 3D-modeling software that involves defining a camera.
The sixteen cubes bear their own colors and feature grid-like patterns resembling chessboards. As the effect rotates, each individual cube slowly starts falling very shortly after the cube in front of it begins to fall, and whenever a cube reaches the bottom of where it is allowed to fall toward, it promptly elevates itself back to the top. Since the cubes undergo this perpetual motion as part of a consistent chain, what results is an effect that resembles a rotating set of stairs that is always climbing upward.
Close observation reveals that whenever a cube making up one of the four corners of the arrangement is elevating, the "camera" will have rotated to a point where the arrangement is seen at a right angle and the cube in question is at either the lower left or the upper right.
