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 bifrustum Hexagonal bifrustum The hexagonal bifrustum or truncated hexagonal bipyramid is the fourth in an infinite series of bifrustum polyhedra. It has 12 trapezoid and 2 hexagonal faces. This polyhedron can be constructed by taking a hexagonal dipyramid and truncating the polar axis vertices, making it into two end-to-end frustums. Several types of crystal take this shape. It has also been used in the design of 14-sided dice, which may be used to generate randomly chosen playing cards. It also has application in novelty promotional calendars: one month can appear on each of the trapezoids, and an advertising or other message
