Loopy is our original character. The illustrations are AI-generated with Google Flow from our own character designs; we composed and animated the scenes ourselves; maps, charts and text cards are our own code. Five short shots are AI-generated video clips (Google Flow), trimmed and timed by us. The narrator and Loopy speak with synthetic AI voices (ElevenLabs). The music is our own. Sound effects are partly our own and partly public-domain (CC0) recordings. Spotted a mistake? Tell us in the comments: corrections get pinned.
