Sankakkei Star Tetrahedron seed
diameter: 12 mm with 12 x 3 mm holes.
Sankakkei rod
diameter: 3 mm
length: 64 mm
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.
