youtube contains a lot more than trampolining bears, illegal music videos and "ooh so clever" advertising virals.
It can also be useful and informative. Honest.
Among the youtube channels we like - and one of the few we actively follow - is that from Vitra.
Recently a new film appeared on the Vitra youtube channel; a short review and history of the Aluminium Chairs by Charles and Ray Eames. Not only is the film a wonderful introduction to the Aluminium Chairs, but also allows a rare "behind the scenes" view of the intense and complex production process - yes, they are all constructed by hand - and also provides an interesting insight into the life and work of Ray and Charles Eames.
Enjoy.
