Small nit: the website uses a <video> element and only provides an Ogg Theora video. This means that the video isn't visible in Safari on OS X and iOS, or in Internet Explorer on Windows. In Safari on OS X this results in an empty set of controls being visible for the video element. In Safari on iOS I see a non-functional play button where the video would be. Furthermore, since the <source> element doesn't have a type attribute browsers have no way of knowing up front that they can't play the video and are forced to start loading the video to determine if it's playable.
