“3 Dreams of Black”, an impressive interactive music video written entirely in HTML5, mixing 2D animation, video and 3D graphics using WebGL. All the source is available to look at and learn from, along with plenty of interactive tech demos on the tech page.
On my machine, Google Chrome was the only browser to be able to properly render the HTML5 content; but it is early days for this technology so not too surprised.
There are many more cool examples of HTML5 around, many using Box2DJS - the javascript port of the popular Box2D (as used in Angry Birds)
