此人太牛了！他制作魔方是用车床等机械加工出来的。
作者介紹：http://twistypuzzles.com/articles/spotlight-okamoto.shtml
Matsuyama, in the Ehime Prefecture of Japan, is home to Katsuhiko Okamoto, one of the most innovative twisty puzzle designers in the world. A graduate of Okayama University, he holds a degree in mechanical engineering. Okamoto-san and his father own and operate a sheet metal fabrication shop. This shop is the envy of any craftsman. Okamoto-san owns a large collection of machines for cutting, drilling, shaping, and bending sheet metal and other materials. His shop is nestled in a scenic area between the Shikoku Mountains and the Seto Inland Sea. The Matsuyama airport is a 5 minute drive away. The building, typical of Japanese buildings, is sturdy enough to withstand earthquakes and typhoons.

Metal Sculpture inspired by The Orb. "Welding Practice." |
On the day we meet, the strength of his building is of particular interest. Super-typhoon Dianmu, Chinese for "Mother of Lightning", is two days away. We can feel the winds from this storm already. The air is moist, warm, and clean.
Okamoto-san uses a fabrication technique that is unlike most other custom puzzle producers. He starts with a 2 cm thick slap of black ABS plastic. Using his machines, he cuts this material and shapes it into the complex structures required for a twisty puzzle. As any fabrication expert knows, one secret to consistent quality is precision-made jigs. He builds and uses a variety of jigs.

Mental Pillow. |
In most cases his puzzles start with the core of a production puzzle such as a Rubik's cube or a Meffert's skewb. Over the years, Okamoto-san's skill and the complexity of his puzzles have increased to the point that very little of the production puzzle remains. In some of his latest designs, almost the entire puzzle is composed of custom-made parts.
We have all have seen photos of his creations at puzzle3d.hp.infoseek.co.jp. We covet these beautiful objects. There have been many requests for photos of the internal structures. These requests will go unfulfilled for the moment, as Okamoto-san hopes to commercialize his designs. I will only say that the internals are elegant in their simplicity and functionality.

Handmade puzzles by Katsuhiko Okamoto. |
In his shop, we sit together at a makeshift bench, with a laptop equipped with sophisticated language translation software. Okamoto-san rented this computer so that we can communicate. This Japanese keyboard looks just like a Western keyboard, but somehow, he coaxes it to print Kanji sentences. They are totally incomprehensible to me. One click, and the English translation magically appears.
Roll-up doors and windows are flung wide open. With Dianmu still far away, a gentle breeze puffs at puzzle drawings and notes. We quickly reach for something to serve as a paperweight. Here, I grab a puzzle. I gaze at the paperweight. It is a Master Skewb. I am awestruck by the beauty and feel of this object. My eye drifts to another puzzle close by. The Master Pyraminx. Carefully I lift it, afraid to turn it, afraid I might harm it in some way. Okamoto-san takes it from me, and unceremoniously twists it in several moves, lightning fast. There is nothing fragile about these puzzles. They are substantial and sturdy, like this building.

The master in his shop. |
I asked him about his first experience with the Rubik's Cube. "I played with a Rubik's cube first in 1980. Although I was a high school student in those days, I found the solution method by myself. However, that solution method was not efficient, and it took a long time to solve. I can solve it only by that solution method even now." (Almost none of the contestants I talked to in Toronto at the 2003 Rubik's Cube Championships developed their own solutions unless they used a computer.) He developed an interest in modifying puzzles, he says, "When I saw an Octagon Cube for the first time on the Internet, I happened to think, I can make that myself! I was lucky that the 100 yen cube was put on the market in Japan." (The 100 yen shop is similar to dollar stores in the US and Canada.)
Okamoto-san is a family man, with a wife and three sons. "I like play my acoustic guitar, and I like the Beatles, Star Trek (TNG), card magic, and mathematics. I respect Einstein, Feynman, Escher, and Erno Rubik."
When asked what inspires his ideas for new puzzles, Okamoto replies, "I cannot explain it well. An idea may flash suddenly, or it may develop after much soul-searching. In many cases, if one good idea appears, other related ideas will appear one after another. So always I have many ideas and I can't keep up with production."
Okamoto-san is an active participant in a Japanese internet puzzle brain-trust, composed of Hiroshi Ishino, Hiroaki Koyama, and Kazuhiro Watanabe. This team is a font of challenging ideas, and Okamoto-san converts these thoughts into physical reality.
Many of us at the Twisty Forum have mourned the short supply of puzzles like the Master Pyraminx, Lattice Cube, and Master Skewb. Unfortunately the jig he used to produce the Master Pyraminx wore out quickly, and he has not had time to build more jigs. Someone asked him, "Do you plan to produce more of Tony Fisher's designs like the Container Cube?" "No," he answers. "I have too many ideas of my own. There aren't enough hours in a day to produce all the puzzles I have created in my mind. From now on, I only produce my own designs."
As an avid twisty collector, I can only hope that somewhere there is a puzzle manufacturer who can find a way to mass-produce Okamoto's fabulous ideas, so that we can all experience the joy of twisting an Okamoto Original of our own.

这老伙计很牛B啊!!![em05]
好的构思，好的设备，才能做出好的魔方。
这个十二轴的中心块隐藏了，中心块成了轨道。感觉原来的十二面体魔方好。

这个可能是另外一个人制作的：Length of a side 1 3/4" (45 mm), height 4" (100 mm).

冈本胜彦这个日本人又出新品种魔方了，是八轴的。太牛了，此人算是魔方结构设计的顶级高手！虽然我对日本人没什么好感，但他的才能我是不服不行啊。

要用代理
以前看到的八轴魔方如魔花、鸭嘴兽魔方等都是八轴一阶魔方 ，是两旋转面相交一个块，所以复原很简单。这种八轴魔方，两旋转面相交的块有7个块（这只是表面上的块），这难度增加太多了。
由于是八轴魔方，它有个特点就是四个旋转面共用一个角块。而普通三阶是三个旋转面共用一个角块。
两旋转面相交珠7个块中，一个是棱块，两个是角块，还是四个是不明属性的块。这就增加很多不确定的变化因素，估计这魔方以后会成为一种经典魔方！

是不是这样来对应两种多面体：

见：高级四轴六面体魔方http://bbs.mf8-china.com/dispbbs.asp?boardID=5&ID=773&page=1
这种我以前以为是四轴六面体的旋转面之处加设轨道制成的。难道也能用八轴的结构，想起来也不奇怪，四轴与八轴是很有血缘的。
我的计算结果就是这魔方了，这下我真的要糊涂了。

[em17]我这话有错“每个旋转面延长到外框的正六面体上时，不会出现交叉的”。
八面体魔方中块的旁边有三个旋转面，这三个旋转面延长时会相交的，相交后中块就被隐藏起来了，形成一个外切属性的块了，就成了外框的正六面体上的角块。
啊，26楼说的那帖子我还跟过帖，今天根本没联想起来，当时的跟帖真乃“有口无心”。
上面的工作我就不必计算下去了，但已做的工作可用于区分8个旋转面：
不知是否符合实际。此外，烟兄觉得如何？如果8个旋转面是这样的话，您是否要对27楼的话作什么修改？

六面体的角块与八面体魔方的中块是两种不同属性的块了。
我还是希望乌木先生继续算下去，我是想知道我的算法是否有误。其实我只算出八面体角块在六面体上的形状比例，其它都是推想出来的。
[em06]您贴出的照片无疑是我的救命稻草，好像没劲道去设法计算了。其实上面的叙述也是不严格的，有的是想当然的。再马虎画个图交差算了：

这两款魔方旋转面是一样的，但表面上的块变化是不一样的。
八面体魔方的中块在六面体的表面上是看不到的，被隐藏在六面体内部了。
六面体魔方的角块在八面体魔方上是找不到对应的块，六面体魔方的角块与八面体魔方的中块是不同属性的块。其它的块倒是可以一一对应上的。

26楼的图我用了1个小时才画出来，让我终于搞清楚两种魔方之间的复杂关系。
八面体的可确定是八轴魔方，六面体的用4轴来设计结构会更容易一点。用八轴来设计应该也行，但结构复杂很多。
