OPTICKS is a live radio transmission performance between the Earth and the Moon during which images are sent to the Moon and back as radio signals. The project has been realized by visual artist
Daniela de Paulis (IT/NL) in collaboration with Jan van Muijlwijk and the CAMRAS radio amateurs association based at Dwingeloo radio telescope (NL). Each live performance is made possible thanks to the collaboration of radio enthusiasts Howard Ling (UK), Bruce Halász (Brazil) and Daniel Gautschi (CH).
OPTICKS employes a technology called Earth-Moon-Earth or Moonbounce, developed shortly after WWII by the US Military as a form of reliable radio communication also used for espionage
purposes. EME uses the Moon as a natural reflector for radio signals.
In October 2009 Daniela de Paulis and Jan van Muijlwijk started pioneering a new application of Moonbounce technology, called Visual Moonbounce, which allows sending images to the Moon
and back, combining Radio Astronomy with amateur radio technologies.
