YouTube celebrates Earth Hour


    I will not say that this is some kind of extraordinary event, but I liked the way to attract the attention of visitors.

    Earth Hour is quite an interesting phenomenon, a kind of flash mob on an international scale. If someone is not familiar, then the details can be read on the project page .
    Actually, in addition to placing an interactive switch on each page, YouTube also created a page dedicated to the event.
