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 crystal family Hexagonal crystal family In crystallography, the hexagonal crystal family is one of the 6 crystal families, which includes 2 crystal systems (hexagonal and trigonal) and 2 lattice systems (hexagonal and rhombohedral). The hexagonal crystal family consists of the 12 point groups such that at least one of their space groups has the hexagonal lattice as underlying lattice, and is the union of the hexagonal crystal system and the trigonal crystal system. There are 52 space groups associated with it, which are exactly those whose Bravais lattice is either hexagonal or rhombohedral. The hexagonal crystal family consists of two lattice systems:
