: Use intuitive, non-mathematical folds to refine the base into a realistic, finished form. 4. Technical Tools
: The areas between creases can be colored with only two colors without same-colored regions touching.
: This refers to bases where all flaps (appendages) originate from a single central axis, a hallmark of many of Lang's super-complex designs. 3. The Design Workflow Lang suggests a workflow that moves from logic to art:
: Any valid crease pattern must follow strict mathematical rules:
