SOMA Video

Now however, Ronald Deckert and his friends at have created the most beautifull video of the SOMA puzzle.

Message to you all:
Any letter or Email you send to me, will be answered quickly.
However I am slow (Very slow)(as molassas in winter) to get anything put on my web pages.
The reason? well - being a college teacher in mathematics, electronics and technology.
Requires a huge effort in reading, preparing etc. so... the SOMA page comes second.

What is SOMA ?

Problems worthy of attack, Prove their worth by hitting back. (Piet Hein)

From time to time, man have tried to construct a threedimensional puzzle.
In no circumstances has it, succeeded so well as with the SOMA cube, invented by the Danish Author Piet Hein.

If you recognize this, Then you know the power of SOMA.
If you don't - then read this web site.

Having the seven Soma pieces in hand, first try to form the infamous 3x3x3 cube. There are 240 independent ways of making this cube. Aside from cubes, there are thousands of geometric shapes that can be created from the seven simple Soma pieces.
Within the Figure pages, there are many figures (ALL that I know actually) which can be built using the SOMA pieces. Some of the figures will require your imagination to figure out where unseen cubes or holes belong. When you have succeeded in making figures from these pages, try to develop some of your own.

If you have any new figures, then please let me know.
