Summary

This article explores the Canon Cat, an obscure 1987 computer that featured a unique document-centric interface designed by Jef Raskin. The author recreates and analyzes this minimalist interface, which eliminated traditional applications and file systems in favor of a single continuous document workspace. The Canon Cat used special keys for navigation and commands, treating all content as part of one large document. The article examines how this interface influenced modern computing conventions and what lessons can be learned from its approach to user experience design.
