Ricardo “Mr.doob” Cabello headed up the programming behind the amazing Arcade Fire interactive video The Wilderness Downtown, which was built using HTML5 and JavaScript. He’s documented how the video was made on his blog, and it’s worth reading for JavaScript hackers. A few years ago, I worked on a project that replaced a Flash-based promotional application for a health insurance company with a version built using JavaScript and HTML. The end result wound up being pretty decent, but my main impression at the end was that it was a ton of work for results that fell short of the original Flash application in terms of dynamic impact. I attribute their more impressive results to the fact that they didn’t have to deal with Internet Explorer 6. Hat tip, Webmonkey.
