> Inside this book, you can not only read the code examples, but edit some of them inline and instantly see the results. This book is an HTML5 application. It uses Application Cache to save itself on your device the moment you open it. It uses Local Storage to save any changes you make to the code examples. It’s using the video and audio elements to play screencasts and other media. And in order to teach you about Geolocation, Canvas, SVG, and other APIs, it uses those APIs in the demos.

I expect more of this. I’m surprised I haven’t seen any designers releasing their portfolios as mobile apps (native or otherwise).
