Doctor Who Live was a continuation of the 1973 story Carnival of Monsters.
The picture on the left is Vorg’s Miniscope that he won at the Great Wallarian Exhibition in a game of chance.
The Miniscope is a machine capable of minimising creatures and their environments. It then keeps the creatures trapped in their own sections inside the machine. The 3rd Doctor explained that the Miniscopes were banned by the Time Lords because of the cruelty involved. The picture above shows the TARDIS growing because it’s been taken out of the Miniscopes compression field.
In Doctor Who Live the machine is referred to as a Minimiser and is strapped to Vorgenson’s arm. Vorgenson is Vorgs son and hopes to meet the Doctor one day.
