I found an exciting project via Facebook today, Faces of Millions.
What's this all about?
Faces of Millions is a project which aims to create the biggest photo mosaic yet, that will be about 30x30ft big (approx. 10x10m or 3 stories high).
It will be made of about 300 usual size posters, which will have fingernail sized photos of YOU, YOUR FRIENDS and all the OTHER PEOPLE who take part (about a million of them).
You can participate immediately by visiting the site and uploading a photo of yourself.
