This installation was commissioned by Centre for Arts & Science as a part of their contribution to the Harbour Festival in Odense, 2012.
The theme was H.C. Ørsted, who is known for (a lot of things, including) discovering electro magnetism. As most electronic devices, the installation relies on electro magnetic concepts, such as electro magnetic coils, electro magnetic resonance etc.
The choice of lab equipment as sound objects was made to keep emphasize the scientific context... And because it looks nice and sounds cool.
Several hundred kids, parents, grand parents, teenagers etc. grabbed the pen and gave a small improvisation during the weekend.
