operate on shapes that are not predefined in a grammar but
emerge, or are formed, from any parts of shapes generated
through rule applications”

was computed using the
implementation, which
was able to incorporate
curvilinear basic
elements in their
maximal representation
and to support shape
emergence. It was used
to generate designs in
the original corpus and
also new designs using
the same shape rules,
arguably in the same
style too.”
