Lissajous Installation

Lissajous Installation, 2016, Analog synthesizer circuits designed and built by the artist, modified CRT-televisions, speakers, ferro-type photographs.

Analog synthesizer circuits designed and built by the artist, modified CRT-televisions, speakers, ferro-type photographs.

An audio visual installation where a real-time synthesized sound scape is made visible with modified CRT-tube televisions. The analog audio synthesizers sculpt electricity into waveforms that are played as a sound. The same waveforms also control magnetic fields that bend an electron beam inside the CRT-tube. The two tone signals are used to direct the beam horizontally and vertically, drawing so called Lissajous Figures on to the screen.

Since the whole process from electricity to sound and image is analog, it constantly contains small amounts of noise and errors due to, for example, background radiation, magnetic fields, and electricity network fluctuations. Therefore, the artwork is completely time and place specific.

The installation also includes direct exposures from the screens to photographic plates. The ferrotype photography is a direct exposure process where the image is directly exposed to the metal plate without the negative intermediate stage. Therefore, there can only be one copy of every picture that can not be reproduced.

All the techniques used in the work have existed in some form and are in use since the late 19th century.

The installation was shown in LUX In in Helsinki in january 2017, and the ferrotype photos were shown  in Rytmitaju exhibition in art museum of Hyvinkää in 2017.
