MARCEL DUCHAMP

Disques Avec Spirales (Rotorelief)

1926 Paris

The Rotoreliefs first appeared in the film Anemic Cinema where they alternate with discs bearing inscriptions. The discs were meant to be placed on a record-player according to the following instructions:

"The disc should turn at an approximate speed of 331/ 3 revolutions per minute, this will give an impression of depth, and the optical illusion will be more intense with one eye than with two!" M.D
