Castles: Responsive Parallax Landscape
Castles is a responsive parallax landscape made with PixiJS, an open source, cross browser JavaScript 2D WebGL graphics library with canvas fallback.
Resizing your screen by dragging the preview pane adds and removes elements in the landscape. Different screen sizes definitely change the way the landscape looks. You can even hover your mouse pointer left to right to zoom in and zoom out.
