Ferrofluid installation "proxemics"

Movement near the ferro fluid influences its shape
Author: Alka Cappellazzo, Mailand, Italy, [email protected]
The goal of my interactive installation "proxemics" is the close observation of the fascinating ferro fluid in a glass container.
The proximity sensor measures movement outside of the glass (e.g. approaching hands) and passes the information on to an Arduino board, which steers two flat disc magnets S-25-05-N and sets them in motion. The magnetic field of the magnets influences the movement of the ferro fluid and causes rather spectacular shapes and bubbles.
