The blocks will shift and twist around in every plane. They make cubes or rectangles of course, but beyond that you can use your imagination to make wondrous shapes, particularly with the longer models. Great tool to develop dexterity skills, focus, and creativity. Beyond the cube, we provide 18 other shapes you can try and make. The 64 block makes a 4x4x4 cube and who knows what else. This design has been called "Fidget blocks" in some craft books and is usually quite short with very small blocks. We have tried to take this concept to a whole new level but making a high quality product with comfortably large blocks in lengths long enough to permit creative shapes to be made.
