"Orbita"-installation consists of a stainless steel
ball 40 cm of diameter slowly moving around circular stainless
steel tracks 8 m of diameter. In the centre point of the tracks
there is a single light bulb, the only light in the space,
which casts a shadow of the moving ball to the surrounding
walls. The sound of the rolling ball is picked up with contact
microphones attached to the tracks. Then it is amplified and
played back real time through speakers in the corners of the
exhibition space.
The constant movement of the ball is possible because of gravitational
pull and minimal friction. There are three servo motors along
the tracks on equal distance of each other pulling the tracks
closer together just when the ball is passing by. This lifts
the ball a little and it starts to run "downhill"
where the tracks are wider from each other, gathering more
speed. This extra speed is enough to keep the ball rolling
until the next servo motor.
