What a wonderful project. The folk at Paravel have taken the Sherlock novel A Scandal in Bohemia and recreated it as a bespoke website. Of course, the whole site is beautifully designed, but the real showstopper here is their (light!) usage of animation and sound. There's something engrossing about reading a chapter set on a wet winter's night and hearing the sound of rain on window panels in the background.
That's the kind of interactivity that the web was built for and I love it. (It's also a cracking argument for copyright expiration and public domain art works.)
