Gallery Image These K'nex constructions were the most fun because they became another toy in themselves! To create K'nex pieces based on the Soma puzzle cube, it was necessary to form adjoined cubelets so that pieces would fit together properly (in other words, it was not enough to simply double the dimensions of cubic areas). This becomes evident when thinking of the entire Soma cube (Image 5) as consisting of 27 identically-sized cubelets. The composite image in the first Soma link in the gallery page contains a cut-away view of one of these cubelets, showing how rigid connections were made using internal white rods and longer rods between opposing outer walls. The combination of white rod and red connector approximated external corners. This image shows the classic Soma design called Tower 2.
