Joost Rekveld: #19

#19 is a light machine in which images are produced through interference. The interplay between the time lag of our eye and the fast rotation of a pulsating lightsource results in ever fluctuating ornaments that can be controlled in real time. The principle of this installation was inspired by the experiments that Chevalier d'Arcy and Joseph Plateau did in the seventeenth and eighteenth century respectively. They tried to measure the temporal response of the human eye by confronting it with spinning coloured disks or revolving, glowing coals. These experiments were at the basis of the later inventions of cinema and television.
