The Roots

The Roots, a typographic piece created for the Keystone Design Union. The KDU espouses many masonic ideals and is connected to the Freemasons of New York. Scottish Thistle, Irish Clover, and British and American Roses reflect the entwined historical roots of the Freemasonry organisation.

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.

## Area and volume

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

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

## 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:

 Dodecahedron Truncated dodecahedron Icosidodecahedron Truncated icosahedron 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.

I finally put together a personal site for my design and illustration work with hopes of pushing the less commercial side creatively and highlighting the less corporate side of my body of design.

## Process

Oct 2010 / № 5752

Roots.

For all my illustrations, I like to document the whole process, from initial sketches, notes, experiments and doodlings to the final piece. This was initially born out of a fascination as to how many of my favorite artists created their work and for a process that can be very time consuming, it’s a relief to see where you have come from.

Below are a few shots of a work in progress, my own take on the Keystone Design Union’s logo. Most of my work is half planned half evolving at the time and this piece still has a fair way to go.

A brief rationale: Scottish Thistle, Irish Clover, and British and American Roses reflecting the entwined historical roots of the Masonry organisation – and it’s part in the inspiration/creation of the KDU.

## Laundry! / Steve Aoki / THE KDU x Hennessy

Oct 2010 / № 5688

This project took almost all year to come together but the results are glorious. The Kdu hq in brooklyn lead by David Gensler, Lex and the team spearheaded this collaboration between a bunch of talented musicians and artists inlcuding myself to create these custom hennessy bottles. Here is one I created with dj steve aoki. For more info about the project and other artists involved click here. Seriously big ups to The Kdu for this opportunity.

## YAW Typeface

Oct 2010 / № 5490

YAW is the new experimental typeface. It is a bitmap, full color typeface. This time around, is a mixture of hand drawn anatomy parts and custom made brushes, with a strong graphical language. Stay tuned for the font release later this year!

## Paris, France

Sep 2010 / № 5088

After Cognac I traveled via train to Paris. The Roots were being film for www.nowness.com on the train by Oliver and Adam, two amazing photographers from London. I only had two days, which was more than enough, since Paris was experiencing one of the hottest heat waves in its history. I will admit, Paris lives up to the hype. It is a beautiful city with amazing light, architecture and the obvious rich history.

## Nooka Studio Visit – NYC

Sep 2010 / № 5068

Recently stopped by the Nooka Design Studios to visit my friend and KDU member, Matt Waldman.
The studio is inspiring and I had a chance to see Matt’s most recent art sculptures for an upcoming show in LA.

Keep your eyes open for some future KDU x Nooka “something something” special.
