The 16-bit digital audio recording of the Banna creek, which erodes the Pianalto region near Turin (Italy), is used to control sixteen electrovalves suspended on a mass of soil from the same area.


When a bit is 0, the corresponding electrovalve is kept close; when bits equal 1, the valves  release a small quantity of water.


The mass of soil gradually collapses and melts down over the days,
creating a landscape on a smaller scale.
