WordPress users that have been interested to explore some of what HTML5 has to offer should check out the latest post from Sameer Borate. He shows how to embed a HTML5 Canvas element you can use to make a "drawable" area of your page. You can test to see if your browser supports it by scrolling to the end of the post.

Only if partially, but HTML 5 is slowly getting increased support from various browsers. Some of the HTML 5 features like ‘canvas’ and ‘video’ are supported by browsers like Firefox, Safari, Google Chrome and Opera. [...] The Canvas element consists of a drawable region defined in HTML on which you can dynamically draw graphics and animations using Javascript. The canvas API provides a nice set of drawing functions to play with.

His example detects to see if the browser has canvas support (using Modernizr), creates a div container to hold the region and creates a Javascript to define the canvas as a 520 by 220 pixel box. The animation should be loaded automatically.
