The ingenuity of the human race has been key to our evolutionary development and survival. Doctor Who exemplifies this important characteristic both on and off screen. Behind the camera, everyday objects and materials such as bubble wrap (Ark In Space) can be gold dust to a producer as a cheap and effective way to dress a set or create a prop or monster. The innovation doesnt stop there, either. The work of the Radiophonic Workshop ably demonstrates that creative new sounds can be found in the most surprising of ways. Running a coin down a piano string and slowing the resultant noise down to create the dematerialising sound of the TARDIS is perhaps the most famous of their accidental discoveries. It has been joined by many more over the years. The ordinary becoming extraordinary is a recurring theme in front of the camera, too. A police box, once an everyday sight on the streets of Britain, has become a multi-dimensional time and space ship. From jelly babies to jammy dodgers, the Doctor is not adverse to using an innocuous item to instil fear throughout the universe. And of all things, a humble screwdriver, takes on 101 different functions.
