I believe that we always have a rhythm beating inside of us, and that this rhythm should be able to express itself while we sit as well.
When sitting suspended, the smallest twitch of a muscle is enough to set the body in motion in a natural rhythm or frequency corresponding to the body's needs and the requirements, physical as well as mental.
Perhaps such movements spark associations to the time when we floated effortlessly in the womb?
This concept was first shown in 1999 at the "Movement - Peter Opsvik" exhibition in Ghent.
