I wanted to explore the possibility of using animated butterflies on a site I was doing, so took the opportunity to try out some animation on Canvas using JavaScript. 

PDF Rendering Using Canvas

I’ve just been read an overview of pdf.js, an experiment to find out if the ISO 32000-1:2008 Portable Document Format can be rendered using HTML5. It’s an interesting idea, and they’re talking about turning it into a Firefox extension in the next few months. It’s apparently a tiny bit faster and more stable than Adobe’s own renderer.
