Slow Growth.

“Slow Growth was the first collab between Daniel J Diggle and Jessica Allan. An example of ‘photoshop tennis’ each artist took turns to progressively add to the image, building it up over time.”

A Hoberman sphere as an icosidodecahedron

In geometry, an icosidodecahedron is a polyhedron with twenty triangular faces and twelve pentagonal faces. An icosidodecahedron has 30 identical vertices, with two triangles and two pentagons meeting at each, and 60 identical edges, each separating a triangle from a pentagon. As such it is one of the Archimedean solids and more particularly, a quasiregular polyhedron.

An icosidodecahedron has icosahedral symmetry, and its first stellation is the compound of a dodecahedron and its dual icosahedron, with the vertices of the icosahedron located at the midpoints of the edges of either. Convenient Cartesian coordinates for the vertices of an icosidodecahedron with unit edges are given by the cyclic permutations of (0,0,±τ), (±1/2, ±τ/2, ±(1+τ)/2), where τ is the golden ratio, (1+√5)/2. Its dual polyhedron is the rhombic triacontahedron. An icosidodecahedron can be split along several planes to form pentagonal rotundae, which belong among the Johnson solids.

In the standard nomenclature used for the Johnson solids, an icosidodecahedron would be called a pentagonal gyrobirotunda.




[edit] Area and volume

The area A and the volume V of the icosidodecahedron of edge length a are:

A = (5sqrt{3}+3sqrt{25+10sqrt{5}}) a^2  approx 29.3059828a^2
V = frac{1}{6} (45+17sqrt{5}) a^3 approx  13.8355259a^3.

[edit] Related polyhedra

The icosidodecahedron is a rectified dodecahedron and also a rectified icosahedron, existing as the full-edge truncation between these regular solids.

The Icosidodecahedron contains 12 pentagons of the dodecahedron and 20 triangles of the icosahedron:

It is also related to the Johnson solid called a pentagonal orthobirotunda created by two pentagonal rotunda connected as mirror images.

Eight uniform star polyhedra share the same vertex arrangement. Of these, two also share the same edge arrangement: the small icosihemidodecahedron (having the triangular faces in common), and the small dodecahemidodecahedron (having the pentagonal faces in common). The vertex arrangement is also shared with the compounds of five octahedra and of five tetrahemihexahedra.

On our way down south from washington to california we made a stop in Dunes city, Oregon where you find wind-sculpted sand dunes towering to 500 feet above sea level. The Oregon Dunes National Recreaion area extends for 40 miles along the Oregon Coast. Formed by the ancient forces of wind, water and time, these dunes are like no others in the world.  It’s an amazing photo location and was defenitly one of my highlights on our trip!

I will post some more photos soon.

As common practice, when traveling, further afield or inland, ’spare time’ is not really down time. To feed creativity and research, it is just natural to gravitate towards ‘living’ creatively deepening Art interests. I have a great admiration for older architecture and construction methods aswell as photography. The opportunity to merge the two is a positive.

201 Ducati Orange 848 Superbike

This is a cool experimental piece. I located a template of a Ducati and really wanted to see a Geometric style decal work around the entire stream of the panels. Also, an idea to complete the graphic used would be to bring it down over the exhaust metals with an ‘anodized’ finish.
