Isoworld can render 3D isometric cubes from three page elements. It takes the identifiers of three page elements and adjusts their CSS transform properties so they form the faces of a cube which appears in the page with the 3D isometric perspective. It can also use a fourth element to be displayed as the shadow of the cube on top of another element which appears as the ground.
Lightning effect JS is an object that can draw a random lightning bolt on the page. It can create a canvas on which a glowing random line similar to lightning bolt is drawn within given page boundaries. The position, color, and thickness of the lightning bolt are configurable parameters.
