This Peep Show is a twenty-first century version of the mutoscope, the early motion picture device which has thrilled viewers since its invention in 1894.
Mutoscopes - known as "What the Butler Saw" Machines - were a popular feature of amusement arcades and pleasure piers in the UK until the introduction of decimal coinage in 1971 made the mechanisms obsolete. The first video arcade game was released in the same year.
Now the ancient idea has been catapulted into the 21st century with the aid of some fairly low digital technology.
So go on, put your face in the hole and turn the handle!
