In the UK, Amnesty International is running an online campaign to drive awareness around its association. As reported on New Media Age the "Make Some Noise" promotion offers online exclusive songs by The Black Eyed Peas, The Cure and Snow Patrol available to download.
Make Some Noise is a mix of music, celebration and action in support of Amnesty International. In particular, the site aims at reducing the number of small arms in civilians' hands. There is also a petition "Join the Million Faces" which invites visitors to submit a photo of their face in order to support the campaign. Unfortunately the invitation is only textual, and the page doesn't offer much information on how the face will be used. Anyway, if you want to find out more about the Million Faces, this is the link to follow.
