The Soma Cube was invented in 1936 by Piet Hein, a Danish poet and puzzle inventor. It represents all possibilities of combining three or four cubes in a ‘notstraight’ way. Its seven pieces can be assembled to form thousands of figures; it is a kind of threedimensional Tangram in this aspect. A first origami version of the Soma Cube was introduced by Steve Biddle in his book ‘The New Origami’. Steve Biddle uses Sonobé units to produce the pieces and arrives at the impressive number of 120 units. Maarten van Gelder has developed a Soma Cube whose pieces are. | The Soma Cube A TelExperiment by Sebastian Marius Kirsch The Soma Cube was invented in 1936 by Piet Hein a Danish poet and puzzle inventor. It represents all possibilities of combining three or four cubes in a not-straight way. Its seven pieces can be assembled to form thousands of figures it is a kind of three-dimensional Tangram in this aspect. A first origami version of the Soma Cube was introduced by Steve Biddle in his book The New Origami . Steve Biddle uses Sonobé units to produce the pieces and arrives at the impressive number of 120 units. Maarten van Gelder has developed a Soma Cube whose pieces are each folded from a single square he uses box pleating techniques developed by Max Huhne. I am presenting a version that is folded from ticker tape. My version gets by with seven long strips of ticker tape each piece requires between 40 and 60 squares. All seven elements are folded from the same principles. Instead of describing each element step-by-step. I will therefore describe the basic elements and the methods of extending them. These methods are then presented with four of the pieces the remaining pieces are only described verbally but are constructed from the elements that have already been described. Before I start. I would like to thank two people Philip Noble whose FlexiCube has contributed much inspiration to tills model and Heinz Strobl. who has worked his way through the whole instruction and who has helped by removing many blunders and mistakes. This is a translation of a German article that originally appeared on no. 22 of der falter the magazine of Origami Deutschland. I dedicate this translation to Jan Polish whom I tried to teach the model at the Wurzburg 97 Convention at one o clock at night but in vain. I hope that my diagrams are clearer than my verbal instructions. 1 Some introductory remarks Symbols v 1997 06 17 17 08 30 skirsch Exp 1996 1997 Sebastian Marius Kirsch. All rights reserved.
