Craftymind.com has published a demonstration of the power available to web developers in the HTML 5 spec. The specification is currently in draft form – actively developed by the W3C. HTML 5 is becoming widely supported by all modern browsers (including Internet Explorer 9). HTML 5 will bring with it the ability to embed video and audio files in web pages without the need for third party plug-ins such as Flash or Silverlight.
The two demos showcase the effect of using JavaScript, canvas and video elements.
