Nice little top, I bought mine in Stailless steel.  It can spin 30+ seconds, but the plastic one will most likely spin less.   

This isn't one of the 4D "Platonic" solids, just a polytope that a friend of mine likes. It has icosahedral and tetrahedral cells.

Beautifull Retro-Rocket (Flash Gordon would have been a huge fan !)! Perfect in different metal texture (we love the gold plated matte or glossy material !).

Let's have something special on your desk ! If you put our retro rocket on your desk, we bet that every person coming in your office will crave to touch it ! We've already tried ;)

This our small size model (6 cm high). This model also exists in medium and big size...

The die's faces are supported by springs meeting in its center.

Shows the duality between Dodecahedron and Icosahedron.
Can be used as a pendant; lanyard not included.

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 (see picture :-) 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).

It's finally finished! When this was half done it looked like this.
And there's a mini version that's much cheaper.

Ever get tired of watching a movie or youtube on your iPad, and all the sound blasts in the wrong direction : away from you!? With Soundsnap you don't have to experience that ever again. Simply place the Soundsnap in the bottom and just enjoy the clear sound, even amplified, coming straight towards you. The Soundsnap works with iPad 2 and the new iPad. It fits with the smart cover in place as well, and you can even charge your iPad while the soundsnap is on. I have designed another version, with holes, making the sound more "full" - adding more depth to the bass. Have a look at my models :-)
