These videos are all hosted with Vimeo, a fantastic service, which as I’m sure you can tell, really blows other services out of the water in terms of quality.
For some reason, the “fullscreen” button which is usually present doesn’t appear on this blog, but it’s possible to go to the vimeo page and watch fullscreen or download higher-quality versions. To do this, you can click on the link I’ve made just below each video. On the video’s homepage, you will be able to watch fullscreen, and even download a higher-quality version.
