“Wave Interference” is a digital art by Robyn Moody presented at Signal Festival 2017 in Prague, Czech Republic.
The kinetic installation Wave Interference consists of 88 neon lights and one organ. It is this old musical instrument which sets everything into motion through its tones and awakens the sound wave which is rocking slowly and gracefully, thanks to light optical illusion.
