HTML is really getting hyped. This site is an example. But here is a very well crafted demo which makes the case. The demo uses exactly 5  statements in HTML5:

<!DOCTYPE html>

<canvas id=”theapt” width=”100″ height=”100″></canvas>

and

<audio id=”audio”>
Your browser does not support the <code>audio</code> element.
</audio>

while all of the rest of the work , and there is a lot of sophisticated Javascripting, is done in jQuery.

Click here and see for your self – CTL+U or find your browser’s View Source command and see the evidence.

Give 9elements.com top marks for a sophisticated integration of graphics, audio and offsite Twitter message retrieval in jQuery.
