The video index site of various Python videos from around the Internet, pyvideo.org was built using Django. The website even using the Bootstrap, from Twitter theme, like my blog here. I would recommend checking out, and you can browse the source code for the site on the developers GitHub page.
The site overall works great, although it does need some touch-ups, mainly on the home page. He could make use of bootstrap's pull down menus, and make the navigation bar stationary. Besides that, it is coming along nicely and can't wait to watch some great Python videos on there. What a great idea for a website.
