Antti Pussinen: Lissajous Black & White, frequency pictures of sound
In mathematics and physics, Lissajous curves are graphs that depict
oscillation and waves and compare the frequency and intensity of two waves.
In a vacuum, energy travels as electromagnetic waves, as oscillating electric and magnetic fields. The combined, reflective and other effects of these energies mould our environment and reality, as well as our visual and auditory sensations.
In these pieces, I study the creation of surfaces and shapes that appear to be simultaneously organic and artificial in images generated using wave patterns. The pieces have been created by directing the cathode ray of modified CRT televisions with sound waves and other electric waves instead of a video signal.
