TARDIS console rooms, in any of the known configurations, is the TARDIS console that holds the instruments that control the ship's functions. The appearance of the primary TARDIS consoles has varied widely but shares common details: hexagonal pedestals with controls around the periphery, and a moveable column (or time rotor as it has been called in the original series and the 2011 episode "The Doctor's Wife") in the centre that bobs rhythmically up and down when the TARDIS is in flight, like a pump or a piston. The secondary console was first seen in season 14 (1976–77) of the original series.
Hexagonal trapezohedron Hexagonal trapezohedron The hexagonal trapezohedron or deltohedron is the fourth in an infinite series of face-uniform polyhedra which are dual polyhedron to the antiprisms. It has twelve faces which are congruent kites. One degree of freedom within D symmetry changes the kites into congruent quadrilaterals with 3 edges lengths. In the limit, one edge of each quadrilateral goes to zero length, and these become bipyramids. Crystal arrangements of atoms can repeat in space with hexagonal trapezohedral cells. If the kites surrounding the two peaks are of different shapes, it can only have C symmetry, order 12. These can be called
