Spiral Drawing Sunrise graphs the rising sun, using sand as its ink.
A small robot is equipped with a solar panel and an hourglass.
It starts moving as the light of the rising sun provides increasing amounts of energy. The machine draws as the sand is flowing, making a spiral pattern over time.
The sand drawing depicts every sunrise unique, as each morning happens only ones. Passersby, who are to late to experience the sunrise in person, can still encounter it via the Spiral Drawing. The performance starts at sunrise and lasts till noon. During these hours an automatic drawing unfolds, writing the sunrise on the pavement.
There is different techniques possible that we used to print the sunrises. For example this messing version we made for Marrakech Biennial
