A video documentation of a site specific performance where the main performers are myself and the sun. I followed the sun as it was moving around and changing the position of the shadows. The performance was going on for three hours and in three different locations in Liepaja during sunrise, midday and sunset.
The sound from the process is generated using photoacoustic principles: the formation of sound waves in accordance with the absorption of light by a material sample. In order to obtain the effect, the light intensity must vary, either periodically (modulated light) or as a single flash (pulsed light). The discovery of the photoacoustic effect was made in 1880 by Alexander Graham Bell, who built the first electronic wireless communication system: the photophone.
