Okay, so I lied, this isn’t ACTUALLY Twitter, however Scott Kildall has created something close to the Twitter experience, except on pegboard in a room… His 2×2 project is an interesting idea to say the least, he has asked people to write their “posts” on 2″x2″ sticky-notes, roll them up, and place them in a hole. Others can add posts to the wall, or read posts that people have written. Check the link for images of the posts or check out the book he has created alongside Victoria Scott that captures the project in whole.
