It was posted on hear a while ago, but I can't seem to find it. It was made like a children's story book; the premise was that we grow up and forget childhood dreams. I hate to use Ask HN like this, but I really want to use it as part of a presentation at school. I'll delete this immediately if anyone responds.
It actually is a children's story book, and I bought a hardcover version the last time it came through here.
