Electrotextile prehispanic computer

The Inca khipu are textile devices for recording information, made of cotton or camelid fiber strings that store data coded as knots. This piece is an open-source textile computer based on the manufacture of astronomical khipu, the cords of which were hand-spun with alpaca wool and copper wire. It functions as an antenna for electromagnetic fields that is connected to an amplifier circuit. The encoded data in it corresponds to: a spectral classification of the stars in the Boötes constellation; a lunar calendar; a solar eclipse; two earthquakes, and the elliptic position of the sun and moon at the time of our births.

This project is a sound and arts interpretation of the technology, wisdom and history of our ancestors, meant to express how the universe is governed by harmonious numerical proportions. What we are hearing now is thus the amplification of inaudible Space, the voices of specters visiting the void, a celestial score, the music of the spheres: the voice of silence.
