interactive installation


valley is a physical-geographic term used to characterize a depression area surrounded by mountains. these geological formations can be protected by the barriers created by the mountains around them, or, on the other hand, be suffocated by them.

this installation takes this concept borrowed to make an analogy with behavior and the relationship between people. as the valleys, humans sometimes also put themselves in a comfortable position, with an apparent protection that would be given by others that surround him. constructed from friends, relatives or even strangers, these imaginary barriers of protection may also have an opposite effect, weakening those who create them, and may even reach an extreme level of dependence behind which one may hide oneself. this person then appears to others as a mere shadow of himself, since he does not show who he really is, and no longer produces his own weapons and defenses.

this installation aims at providing a metaphor of this behavior in the form of light sources of various colors that are blocked by layers of acrylic cut, letting only a small fraction of total light to go outside. this light reaches a 360-degree screen that surrounds the core of the installation. the screen prints the silhouettes of the shapes that are cut in the middle layers of acrylic. as there are three layers, all of them contribute to the obstruction of the passage of light, and the disposition of each one is crucial to the result that appears on the screen. the layers are thus making  the role of the mountains, blocking the information coming from the valley (the lights from the LEDs in the center of the object).



the installation also generates sounds that are directly related to the rotation of the three layers and the color and amount of light emitted by each LED. the three voices “sing” to form melodies and harmonies directly related to each layer, to its position, rotation and speed.

for example, while a layer is spinning, a note is being played. the frequency of this note is linked to its corresponding layer parameters such as position and speed. if two layers rotate, two notes are played simultaneously. three layers form a triad (conventional chord).

the sounds are generated by three small synthesizers, which are controlled by the Arduino board and connected to a speaker. the same impulse that generates sounds, controls the layers rotation and turns the LEDs on, emitting light (and therefore the silhouettes on the screen).

this installation is a generative audiovisual work. its sounds and movements do not repeat, because they are generated using random methods, programmed by algorithms written on the board that controls it. that is, once in operation, it has a life of its own, using the original programming to create its own sounds and images autonomously.

another important aspect of work is that you cannot say which part has priority over the other as its sounds, images and movements are generated exactly at the same time.
