Clockwork

Clockwork was the inner workings of a clock or any similar, mechanical device. It was usually powered by a winding device that, when wound, generated energy through a spring, pendulum or gear to create a motion. Wind-up toys frequently contained clockwork.

Examples of clockwork in the universe includes...

• The Clockwork Soldiers of the Land of Fiction (TV: The Mind Robber)
• The clockwork technology used by Shade Vassily in the 20th century (PROSE: The Clockwise Man)
• The Clockwork Droids, which were 51st century robots (TV: The Girl in the Fireplace)
• The miniature clockwork people created by the Seventh Doctor for his model train set (PROSE: Model Train Set)
