Robert henke & Christopher Bauder made this installation/performance piece called Atom:
A room is filled with deep, evolving noises from a four-channel sound system. An eight-by-eight array of white, self-illuminated spheres floats in space like the atoms of a complex molecule.
Through variable positioning and illumination of each atom, a dynamic display sculpture comes into being, composed of physical objects, patterns of light, and synchronous rhythmic and textural sonic events. Change, sound, and movement converge into a larger form.
The height of each helium balloon is adjusted with a computer-controlled cable winch, whilst the internal illumination is accomplished using dimmable super-bright LEDs, creating a pixel in a warped 8×8 spatial matrix.
The sonic events, the patterns of light, and the movement of the balloons are manipulated in real time as a 45-60 minute-long performance.
