I am building an educational site similar to Salman Khan's http://khanacademy.org
The core of the project is a collection of educational videos posted on Youtube, the site is a means of viewing them, one page per clip.
The front page should contain a categorized collection of all links to the videos.
Preliminary sketches of the pages are attached. No design is requred atm, only functionality.
I would prefer the project done using one of the popular free CMS as the platform.
The project is oriented towards Russian-speaking folk so some knowledge of Russian is a plus but by no means a requirement.
