Joseph Plateau... =)



Joseph Antoine Ferdinand Plateau (14th October 1801 - 15th September 1883) was the first person to demonstrate the illusion of a moving image. To do this he used counter rotating disks with repeating drawn images in small increments of motion on one and regularly spaced slits in the other. To use this you would spin the disks and look through the slits in the reflection of a mirror. This device is called the Phenakistoscope. Here is an example of the device in motion.
