Maybe you've already seen this, but i think its cool, its a project called Don't tell Ashton, and its based on creating an artwork consisting of twitter users avatars. The more followers, the bigger picture is obtained in the framework where all the avatars are collected. There is 1 twitter user who has so many followers that he alone can fill the large frame on the site. And that is Ashton Kutcher. Click here for the website, and here for a video.
