Helmet #1
helmet #1 is a surround light to sound converting apparatus,
that plays with the spatial perception of the user. 11 speakers are
mounted on a grid, with the form of a icosahedron, around the head.
on each vertex of the structure is a small oscillator circuit attached
that converts with ldrs light into sound.
