You are correct, every version except for the "writing desk" had a transparent cylinder that "bobbed" up and down as the TARDIS traveled through the "temporal vortex". The first one that William Hartnell operated had various transulcent and shiny gizmos that slowly rotated. By the time of Tom Baker's era, the "budget" console had three tinted flourescent tubes linked by plastic rings and disks within the column. The "blinking mushroom of death" used transparent plastic spires illuminated from below the column within the console. The "Fox" console, if nothing else, had a beautifully elegant column. It had two separate upper and lower sections, the upper part supported by huge cross sectioned iron girders. Er, that was not the elegant part. What looked interesting was the way a ring of glowing rods interlocked like fingers with the other section, constantly opening and closing as the TARDIS traveled through time. The "bobbing" column is a signature element of the console. It is the one part I will make sure CAN be morphed for animation. Sincerely, Bill
