JS WARS is a classic shoot 'em up written to demonstrate the power of modern Web browsers. It is targeting Firefox 3.5 with its audio/video support and increased performance, and uses the canvas tag. It should work well in other modern Web browsers (supporting the canvas tag), just without the music and sound effects.
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.
noVNC is a VNC client implemented using HTML5 technologies, specifically Canvas and WebSockets. It supports "wss://" encryption (SSL/TLS). For browsers that do not have native WebSockets support, the project includes web-socket-js, a WebSockets emulator using Adobe Flash. In addition, as3crypto has been added to web-socket-js to implement WebSocket SSL/TLS encryption, i.e. the "wss://" URI scheme.
