The software shows sound oscillations as XY matrix functions and creates complex graphics curves. Lissajous graphically describes sound and allow observation of constantly varying signal voltage of two audio signals as function of time. Video generated by sound can be controlled in endless ways by giving to the user the possibility of a whole-new range of interactions.
