A project proposal for Screen City, City of Stavanger, 2013
Wherever it sets foot, the theodolite heralds change.
For centuries this device has been used by the surveyor to measure both urban and rural environments, resulting in Euclidean models used by the planners and developers that shape the world we live in. Song of the Theodolites diverts the forboding gaze of the theodolite to the service of music rather than the ongoing project of transforming and expanding our cities.
Just as a record needle turns grooves into sound, the theodolites at work in this piece are each adapted to function as an architectural stylus, turning measurement of their surrounds directly into haunting song. Fitted with programmable servo-motors, a tiny computer and speaker, the devices cast their gaze over architectural details in carefully trained patterns, turning perceived distance into audible pitch.
The result is an outdoor, multi-channel audiovisual work combining the tradition of contemporary experimental music with laser light and the gestures of animated machines.
Hardware Introduction
Song of the Theodolites involves modifying existing theodolites, fitting them with programmable servo control, a Digital Signal Processor, a GNU/Linux embedded system and single point-source sound output. It is envisaged that between 3 and 7 theodolites will be adapted.
Installation Overview
Between 3 and 7 theodolites would be placed in an urban, public space on pedestrian ground such that audiences can freely move among them. The facades within laser reach of the devices (100m) should be heterogenous in nature; a more planar modern building will result in a very different texture than that of a baroque or rough stone surface. It is envisaged the devices would assume triangle (3) up to star (7) point formations, with the laser range finders scanning outward, speakers at center.
Performance Component
The installation setup process of Song of the Theodolites doubles as a public performance in itself. The artist will dress as a town surveyor - complete with safety clothing, hard hat and clip board - for the day long calibration and composition process. By night-fall the work is activated, performing itself over the course of 2 or 3 hours.
