'surface' always exposed to outside;
it's a spot where contact / friction / collision occurs.
it gives a shape of object.
it's a place where meaning appears.
on my series works 'surface' which is since 1989, I'm having a subject as phenomenon of contact electricity. This is one of them. On this work, I realized a kinetic installation.

materials: hellical spring, stepper motor, loudspeaker, spark
