New way of drawing SOMA (re. SOMAP)

There are many ways of drawing SOMA, and often we see the Isometric form (that is also used on most of these web pages.
Furman Smith will present us for a different way, using sticks and small balls to represent the position of cubes.
You may ask why this is smart? - but read on, you will see that this way is very practical, allowing you to see through the construction, revealing what is normally hidden.

Furman write the following description.
Dear Strangers. Who Also Enjoy the Soma Cube

Here is a way of drawing the cube that I haven't seen elsewhere:

I submitted some similar drawings to the SOMA ADDICT and had a letter back from Parker Brothers Games (4-Jan-1973; Michael W. McCarthy)
saying that it was beyond their means to make a set of clear blocks (clear except for the embedded sticks).
I know that in the two score years since then I could have gotten 27*8=216 little acrylic cubes,
marked some edges, and glued them together and had such a set but my craftperson ship would have been clumsy.

PS: from Thorleif:
You might want to check this page to understand the text. "The complete "SOMAP" is found"
Or some of the other Newsletters about SOMAP.

These drawings are two pages that shows L4d, L4h, R7c, R7d and helps think of how to hop between L4d and L4h as if R and Y were glued together and also L and W glued together.
It also shows moving between R7c and R7d, as hinted in the SOMA ADDICT, by using the mirror images of those (L and Y glued together and R and W). By the way - it reveals the Conway-Guy Diamond.

This is a sketch of a stick figure representation of eight cubes and their reflections the layout of the lower half reflecting the SOMAP layout.
I fear that I have a lot of clutter. (Maybe some day it will be cleaned up.)

Finally is a portion of an Excel worksheet that walks from R7d to L4d. The portion just goes from L2i to L4d but it shows one technique for noting changes.
I can indicate a certain cube and transition and then do a copy and paste and blank out (or dot out) the pieces in the transition.
Then I can think of the fit and type it in. Thus I am left with a record.
Yes, it is rewarding to handle the pieces but I am compulsive and like a record.

Once the moved pieces in the new cube are typed in I can verify the name (on the SOMAP), type the next transition (looking at the SOMAP), copy and dot out, and carry on.

If anyone would like to market a partially clear set and it is ok with the Piet Hein foundation then consider the soma sticks as public domain.
If you can make money from it you are welcome to; you owe me nothing; but public domain prevents anyone from putting a lock on the idea.

By the way - in Oct. 26, 2016 Merv Eberhardt sendt this drawing to Furman Smith
Furman answers: "Friend Merv, What you sent contains what I was looking for and much more...."

Pretty, isn't it ??
