To continue my ongoing explorations into Media Archaeology I modified a discarded little CRT screen, destined to trash and probably pollution and transformed it into an artistic tool on which I can draw shapes using sound signals. In the fashion of Visual Music, I can input two signals for X and Y deflection and create Lissajous shapes. The signals are previously amplified with a cheap stereo amp found on the web. A total of 30 euros to transform trash into lightart 🙂
