Working together with the Dutch HAM Astronomers Jan van Muijlwijk and Harry Keizer (CAMRAS), facilitators of the radio observatory Dwingeloo, we visualized the act of Earth-Moon-Earth communication, or moonbounce in short. Using the moon as a reflector, the radio observatory is used to bounce musical sounds off of the moon, which are used in a musical composition. The moonbounced sounds are visualised using a vibrating mirror, illustrating the act of using the moon as a reflector.

Before satellites were in orbit, the moon was used as satellite, and thus this technique was used from the 1940’s up to the 1960’s, when the first real satellites were launched. Since then, radio amateurs worldwide have been keeping the act of moonbouncing alive.
