TARDIS by producer Barry Letts, who felt that the new roundels resembled washing-up bowls stuck to the wall. However, as fate would have it the set was damaged in storage between production blocks and had to be rebuilt, so this particular design only saw service in the one serial. The TARDIS has at least two console rooms: the primary one most used throughout the programme's history, and the secondary console room used during Season 14 in 1976/77, which has wood panelling and a more antique feel to it. It had been designed to make shooting more comfortable for the camera crew.
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
