• I made this exclusively, from scratch, for a very smart guy who, for posterity, quietly collects all my die designs; I wish he'll make a good fortune out of them, long before I dice :-)
• Has "OPRESCO FECIT FOR COOK - A.D. 2010" inscription on one of the inside faces. I hope he's rich enough so he could afford ordering 2 sets and UPS me one, with his autograph on it :-) And Kevin, if you do, please mention on your order (in bold lettering) that the captive RHOMBIDIE® should be free to move around at will, inside! :-)
• Note: In the 1980's, I've been exploring the duality of Polyhedra while making a series of polyhedral sculptures; I've developed, then, an unique method/theory/theorem on building Platonic and Archimedean Polyhedra out of scrap metal offset plates (to this day, my favorite material for building all kind of models by hand) and machine screws by strictly using only conventional (at the time) drafting tools: (T-square, Triangles, Compass, Protractor, Trigonometer) and an E-Xacto knife. All geometric art seen in my shop is the spin-off of that hands-on research and work; for more info see http://cascador.com/RegularPolyhedra/PolyhedraH
• Keep an eye for the soon to be released 30 faceted RHOMBICTRIACONTAHEDIE® with Roman numerals on it :-)

• Keyring and/or Pendant • For all the "A&H"s out there!

• 32 faceted die • Design based upon the geometry of the Truncated Icosahedron, a.k.a. the Soccer Ball • Hexagonal faces numbered 1 to 20; Pentagonal faces numbered 21 to 32 • Uses the same original construction algorithm as the popular ICODIE and the Dodclock Die • A related design that can be worn as a Pendant

I coined the word "geocube" because this design (assembled from a unique modular element)  is actually based upon the geometry of the cube.

• Note: The unique construction method that I have used in assembling (piece by piece) this model is based upon a Theorem on the Duality of Regular Polyhedra that I have demonstrated in 1981– while creating and building, by hand, a series of polyhedral sculptures. For more info, see:

• Based upon the geometry of the RHOMBICTRIACONTAHEDRON
• 30 faces numbered 1-30; the sum of oposing faces = 31

Shows the duality between the Icosidodecahedron and Rhombictriacontahedron

During the late 70's and early 80' I became highly fascinated by Polyhedra and its Duality.
Intrigued by the little known fact that Plato and Archimedes described their wonderful objects by drawing them with just a stick on the sand, I set up to replicate (well, more or less :-) their extraordinary feat by strictly using only a "T" square, a pair of Compasses, a set of 2 Triangles, and a Ruler.
For the next 5 years I practically lived inside Polyhedra :-) and, what I used to call "The Archimedes' Curse", ended up to be, in fact, "The Archimedes' Blessing"!

The Polyhedral Sculptures depicted below were hand made (from scrap offset plates) and assembled with machine screws from stackable modular pieces. The modules were drawn/designed on a drawing table while strictly using only a "T" square, a pair of Compasses, a set of 2 Triangles, and a Ruler.

Based upon wonderful knowledge I accumulated hands-on during the 1980's while exploring "the extraordinary spatial diversity that emanates from the sublime order and elegant simplicity that is exemplified by the subject of polyhedra." (Quote from the Preface to the wonderful book POLYHEDRA PRIMER by Peter Pearce and Susan Pearce)

I was extremely pleased when, a few years back, Prof. George Hart (Department of Computer Science, Department of Computer Science, STONY BROOK UNIVERSITY) included some of my Polyhedral Sculptures, alongside work by Buckminster Fuller and other great designers in his comprehensive COURSE STUDY: COMPUTER SCIENCE AND SCULPTURE (pg. 39-40, OPRESCO).
