**Sankakkei Star Tetrahedron seed**

diameter: 12 mm with 12 x 3 mm holes.

**Sankakkei rod**

diameter: 3 mm

length: 64 mm

**64 Tetrahedron Cube
**This puzzle holds 63 seeds and 224 rods. This beautiful structure is formed by merging the edges of 8 Star Tetrahedrons together into the 64 Tetrahedron Cube, revealing the new form ‘Vector Equilibrium’ in two scales, the inner core and outer edge.

The 64-Tetrahedron Cube has both sides of the spectrum, the ‘absolute nothingness’ (vector equilibrium) and the absolute expansion (star tetrahedron). It represents the total, the alpha and the omega, the inner and the outer. It also shows how to divide to infinity (in a scale of 8) within a finite boundary. And above all… it’s a beautiful and captivating geometric sculpture to look at!

**Vector Equilibrium
**This puzzle holds 13 seeds and 36 rods. The Vector Equilibrium is formed by pointing 8 tetrahedrons inwards, the exact opposite of the Star Tetrahedron, using the same amount of rods but needs 1 seed less.

The Vector Equilibrium, as its name describes, is the only geometric form wherein all of the vectors are of equal length and angular relationship (60 angles throughout). From a physics standview it represents the ultimate and perfect condition wherein the movement of energy comes to a state of absolute equilibrium, and therefore absolute stillness and nothingness. As Buckminster Fuller states, because of this it is the zero-phase from which all other forms emerge.

The vector equilibrium is the zero starting point for happenings or non happenings: it is the empty theater and empty circus and empty Universe ready to accommodate any act and any audience.

– Buckminster Fuller

**Star Tetrahedron**

This puzzle holds 14 seeds and 36 rods. The star tetrahedron is formed by two big tetrahedrons interlocking in opposite directions, creating an octahedron in the center with eight new small tetrahedrons pointing outwards, making it the exact opposite of the vector equilibrium with 8 tetrahedrons pointing inwards.
