The Burst Engine is an OpenSource vector animation engine for the HTML5 Canvas Element. Burst provides similar web functionality to Flash and contains a layer based animation system like After Effects. Burst uses a very light-weight JavaScript frame, meaning your animations will download unnoticably quick and can be controlled using very simple JavaScript methods.
Besides form controls, alerts & similar simple JavaScript usage, you can almost do anything with the help of JavaScript (& Canvas). Some samples are: * Drag’n drops * Animations * CSS manipulations, Ajax & more.
