Rotating a 3D hyperplane 180 degrees in the middle of seven dimensional Spheritigric Duotorus: (((II)I)((II)I)I) . Start from 4x4 array of 16 spheres, rotate past major pairs stacked 4 high of 8 torii. Implicit surface equation : (sqrt((sqrt(x^2 + y^2) - R1)^2 + z^2) -R2)^2 + (sqrt((sqrt(w^2 + v^2) - R3)^2 + u^2) - R4)^2 + t^2 - R5^2 = 0
