Music of League video

I was just rewatching the AMAZING video riot released of their music collection, and the video that has all of the champions' weapons shuffling by in the background with the animated spell effects as well, and I wanted to know if there would be any way I could have the video!! MUCH WANT. SUCH PRETTY. And i couldn't find any boards or downloads or anything "legal" to get the video in any way. (probably because Riot doesn't want to give it away because it's so AWESOME!) http://promo.na.leagueoflegends.com/en/music-of-league/
