What is LSP about?

LSP is a research trajectory exploring the relationship between sound and three dimensional image by means of laser projection, resulting in live performances and immersive installations. In 1815 Nathaniel Bowditch described a way to produce visual patterns by using a sine wave for the horizontal movement of a point and another sine wave for the vertical movement of that point. The shape of the resulting patterns depends on the frequency and phase relationships of the two sine waves and are known as Lissajous figures, or Bowditch curves.LSP interprets Bowditch's work as starting point to develop real-time relationships between sound and image. The sine waves used to create the visual shapes can, while being within our auditory frequency range, at the same time be interpreted as audio signals and therefor define a direct relationship between sound and image. This means that frequency ratios between sounds, de-tuning and phase shifts have a direct visual counterpart and vice versa.
