I am a retired engineer, computer hobbyist, naive artist and have always been fascinated by geometry. Current computers and sophisticated programs make it possible to create, study and visualise complex structures. For me this is a constant source of challenges and delight.
The topic of this artwork is a playfully treated feature of
non-periodic tilings called growth form. Growth forms are a kind
of neighbourhood relation for 2D or 3D tilings: Let a patch P of a
tiling be a finite set of tiles. Under recently found general
conditions  the nth-generation "immediate neighbours" of P,
scaled by 1/n, form a defined polygon or polyhedron in the
Here the tiling is derived from 30 vectors related to an octahedron 5 compound and the growth form is a convex polyhedron with icosahedral symmetry, 590 vertices, 1260 edges and 672 faces.
