Hello internet people!

After a great absence, here is the latest.

First, an artwork done as the cover to the first single of a Brazilian Hip-Hop band called Start.

A little while ago, Start approached me and the kids at Fuzuê (www.fuzuecomunicativo.com) to put some artwork together for their releases.

So, this is the first, and more are yet to come!

Sorry for the delay in posts. I am back in the KDU studios and grinding away on new projects. Travel and clients have been keeping me busy…
Stay tuned for dozens of new photos series and notes on the recent months.

Wolfbite.

“Wolfbite is the slightly wonkey nail in the plasterboard wall on which to hang the collaborative illustrations we create.”

Web designer and illustrator Daniel J Diggle and fellow illustrator Jessica Allan created Wolfbite as a little home to their creative collaborations and as a place to display future collab’s with other artists too.

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.

It came down to this and another image for the cover, unfortunately the other image was chosen. I was lucky enough to be featured on the cover of the German edition however, as they loved it that much!

Audiobaums release is set to be a twin EP that revolves around Joleas acclaimed debut album Ghostly Figures. The first part of the release will be a collection of remixes of the tracks from the album made by some of Audiobaums favourite electronic artists including Bad Loop, Paul Easy, Recue and more. The genres are to cover more the danceable side of electronic spectrum not forgetting the deeper end either.
