This document introduces a new document format called Polyfoil documents. Polyfoil documents are designed to move beyond the linear structure of printed documents and embrace more complex, multi-dimensional structures. They allow for cyclical, branching, and interconnected elements. This format is presented as an innovation that promotes in-depth understanding over superficial knowledge by allowing readers to construct document versions based on their own understanding, without distractions. Patent protection is sought for Polyfoil documents to encourage their development and spread, as the inventor believes they can trigger new ideas and are an important idea that may otherwise remain undeveloped without protection.
