From the developer:
CocoaTADS is a port of the HTML TADS interpreter, a multimedia interactive-fiction platform, allowing you to play text adventure games. It allows not only text but also graphics, sound, and even animation. CocoaTADS is currently extremely pre-beta, and there are no guarantees on how well it will work.
