This work derives from a sketch of birds scattering from a tree. Each concentric polygon starts with one radius from the central point. Each succeeding radius is drawn at a Golden Section proportion angle to the previous one. Outer ends of each set of radii are joined to make an irregular polygon. Each new polygon starts at a Golden Section proportion from the last side of the previous polygon. The triangles are placed in sequence. Quite dark green middle of work lightens outwards and turns blue. The colours are reversed for the triangles and for the exit shape.
