"helmet #1 - #3" is a series of different pieces of headgear that deals with spatial perception and the possibilities for transforming it. In #1 – #3, three identical devices in the form of icosahedrons convert the spatial ambient light into a specific sound collage. In each corner of the geometric structure is a loudspeaker directed inward and a simple oscillator that sonifies the enviornmental light conditions in an audible sawtooth soundwave inside the gadget. Acoustic measurements are then taken of the environment as the device responds to the given reality of the space and the local situation in which the “receivers” find themselves as they wander through the area.
