Here the vulgar eye will see nothing but Obscurity and will despair considerably.

Scrying is a technique of divination and revelation, of producing visions, perhaps of the future, through prolonged gaze at an object, usually of crystal or liquid nature. Scrying was famously practiced by the 16th century astronomer, mathematician and alchemist John Dee with the assistance of presumed impostor Edward Kelley, using a mirror of obsidian amongst other devices.

The scrying project presents itself as a generic, modular platform for artists and theorists working with both code and electromagnetic phenomena. Of central concern is some kind of intervention within often complex spectral ecologies; for example, measurement of the strength of EM fields, transmission and reception amongst mobile networks of devices, large-scale intervention through the production of high field strength emissions, mapping of intensities and blind city flaneur.

At present scrying consists of a modular hardware platform, core C library for hardware access, test logging applications and a Scheme interpreter.

example use and notes


artistic and research use

1] code broadcast stations:

Code is modulated and broadcast by AM or FM transmitters from covert, city-wide, solar-powered scrying stations. scryers move through the city [with devices] - code runs and is modified by architectural and urban EM environmental issues.

2] LRA: Local Resonance Amplifier:

Local Resonance Amplifiers (LRA) are parasitic city devices (PCD) which amplify and dislocate wide band electromagnetic (EM) emissions or signals. Mushroomed LRA devices serve as mute witness, creating significant physical and symbolic imbalances within complex city-wide spectral ecologies: subtle interactions between physical constructions, communication technologies (wireless networks, mobile phone networks, RFID, television, radio, radar), power lines and lines of transmission, biological phenomena, and geologic properties.

3] geologic/archeologic mapping:


Re-mapping techniques/methods from the discipline of archaeological geophysics to use present EM emissions to divine the (hidden) past of an urban location.


For example:

  • Electromagnetic methods: EM conductivity

Electromagnetic methods measure the response of the ground due to the propagation of an electromagnetic wave. A transmitter coil is used to generate an electromagnetic field which propagates into the subsurface. As the EM wave travels through the ground, eddy currents are induced in conductors in the subsurface. These eddy currents then generate a secondary magnetic field which is detected by a receiver. Usually, both the primary and secondary fields are detected by the receiver.

scrying walk

In the context of the scrying Gijon walk, the platform was used with a simple logging software to map broad spectrum EM field strength within the centre of (old) Gijon surrounding the Pelayo statue. An attempt was made to access both the past and future of this site through speculative appropriation of the techniques of geophysical archaeology and a relation to Burrough's cut up/Hugh Everett's theory of Many Worlds. In practical terms a broadband log periodic antenna was attached to a scrying board equipped with GPS and wide spectrum signal strength board. The platform was attached to the laptop and minicom serial communication software was used to issue logging commands and to make sure the GPS had locked to a signal. The laptop was detached and the board and both local and GPS antenna was carried in a spiral walk around the main square in the rain for around twenty minutes. At this point the laptop was re-attached and minicom again used to download the logged data (position and field strength) to the laptop. The data was cleaned up or massaged, to match a format suiting the gnuplot analysis software and a 2D representational graph of field strength against position was constructed using both GNU Emacs and gnuplot. Rough correlations between the perceived physical structures (a large fountain) and environmental issues (presence of cars surrounding the fountain), as well as possible discovery of several underground fish salting and farming chambers (from Roman times) were also discussed.
