3 times 4 is a non-physical sound installation that converts movement into sound and image reproduced in real-time on the worldwide web.
A webcam put up at a public place forms the point of departure of the installation. The movements of pedestrians, cars and cyclists are registered by the webcam and converted into sound and image.
The image of the webcam is reduced to 12 surfaces: 3 x 4. To each surface a sound and image is attached. When movement is detected within the scope of the webcam, this movement is linked to the associated surface and the related sound and image are evoked.
