'Interactive' Outdoor in Amsterdam

Artis babyboom from Dawn Amsterdam on Vimeo.

Dawn in Amsterdam have done this really sweet outdoor campaign for Artis - the Zoo in Amsterdam.
The posters are made up of stickers that can be removed like kids sticker books and placed all over the city. Watch the film.
It's a great display of how you can still have interactivity in 'traditional' media.

I saw this on Advertblog.
