Wind speed data from Saint Petersburg’s weather station drives the stepper motor to rotate the stone. The stone gradually turns into sand. In real time, this natural process occurs constantly and is called Corrasion. This work is an attempt to realize the power of processes occurring in nature and their tremendous scale. In the nonhuman time scale period, densely stacked matter was formed. A stone is grating a stone, and the history of the Earth is revealing and immediately disappearing while turning into fine fractions — to be rearranged in the remote future into a new entity.
