Light responsive projecting screen (left) and Ink Machine (right)

In Dripping sounds the evolving movement of drops of ink expanding into clear water determines the sound filling the space in an attempt to establish correspondences among the messages of dissimilar nature we perceive by our sense organs and to reveal the chaos surrounding us as the clumsiness to perceive the underlying order of nature.

The "Dripping Machine" and the "Sound Screen" are the two apparatus the installation is comprised of. The first one, constituted by A 0,22 gallons water container, a lighting and two lenses device, a ink dripping system and a microcontrolled flushing mechanism, is in charge of the following three tasks; the optical projection of the enlarged image of the drop, the drop dispensing and the water renovation cycle of the container where the ink is dripped.

The second one translates the moving image projected over its surface into sound via the twenty photosensitive independent modules mounted in its backside. The modules, wired independently to twenty speakers encircling the screen, are distributed in an equidistant grid of four columns by six rows, each row comprises four units connected in parallel; four individual modules and an electronic circuit that provides an exclusive sound.

Having the same natural source, the five different sounds are dissimilar in pitch, increasing vertically from low frequency in the underside of the screen to high in the upper one in an array of six tones. The photocapacitor mounted in each module determines the volume of the sound it transmits through the speaker. The quantity of light this device collects is inversely equivalent to the volume of the wave it emits and vice versa.

Therefore the projected image of the drop, while it is spreading out and ascending (the image is flipped due to the combination of concave lenses), activates the sensors installed over the screen and produces a sound that goes from low to high frequency values

In "Dripping Sounds" I'm trying to create through the translation into sound of data collected from a natural system a sedimentary process that allows the user to find the relation between the organic behavior of the ink and the resulting sound.
