Amsterdam Light Festival 2015 featured “Melody Dots II”, a light artwork by Yoko Seyama and Dirk Haubrich in Amsterdam.
This seems to be a Gesammtkunstwerk in which all kinds of arts come together. It is a sculpture consisting of a semi-circular screen and a mobile with colourful disks. It is also kinetic art that moves in the wind.
