"The Zimmer Twins" is known for its unique format, which allows users to join in online to get their work to be shown on television. Children are invited to make and share 1-minute animated episodes using a story editor and library of animation. The audience creates endings to short "story-starters" that are professionally produced. Children tell their stories by choosing actions, characters, props and backgrounds. They can also add their own dialog and on-screen text. New clips are sometimes added.
