Min Vid is a Firefox add-on that gives you complete control over the videos in your browser. You can pop out, sticky, resize, and drag videos anywhere within the browser - it even stays visible when you switch tabs, so you can keep watching while you browse.
This is an experiment - seeing what happens when users have total control over the media they're consuming on the web. Users should be able to consume content in whatever way they feel comfortable. In the future we may be exploring these concepts with other forms of media, such as audio or pdfs.
