SpiralSet now available as a universal iOS app...
Requirements: iPad 2 or later, iPhone 4s or later, iPod Touch (5th generation) or later.
The three coloured balls contained within the SpiralSet structure determine the timbre of the sound output. Tilt the structure to influence the motion of the balls, to control the sound produced. Each ball controls a granular voice, creating the sound. The sound develops and changes in relation to the position and movement of each ball. Different sections of the SpiralSet tube network have different sound characteristics. Try exploring each of the different spiral sections.
HINT: Try making the balls move slowly to create subtly shifting ambient drones, or make them stop moving completely to 'freeze' the sound.
