Audio and audio-visual installations. 

Negative Differential Resistance (2013)

This work is a room-sized, computer-controlled audiovisual sculpture. An array of eight amplified and electroncally processed fluorescent lamps, whose patterns of activity are structured around generative sets of numerically encoded gestures and scenes, Negative Differential Resistance is a study in temporal relationships of stability and instability.

In its visual and auditory exposure of its own workings, light is presented in all its corporality, not as ethereal or transcendent substance, but as the physical result of switches closing and power plants humming, perturbation as much as illumination, the consequence of destruction and the signifier of creation.

Deriving its formal aspects from the idea of the binary -- a lamp is either on or off -- and limited to a minimalist palette of white light and 60-cycle hum, this work creates an optical and aural theater whose ultimate topic of investigation is our own awareness: as patternmaker, cognitive agent, and embodiment of time.

Western Electric (2012)

Western Electric is a composition for an array of computer-controlled rotary telephones. Using swarm intelligence and small-world network algorithms, Ostrowski transforms the phones into a flock of obsolete instruments with an atavistic sentience: Not the advanced consciousness of communication devices as we fantasize them, but a primitive will whose intentions are utterly alien to us, expressed in a language of peals and clicks. The Host aims to unfold the formal object of the telephone by reshaping its familiar sonic and social relations, reconsidering it as orchestra, bedlam, hive, and site of exchange.

Scarlet(t) (2011)

Scarlet(t) is a systems-based attempt to isolate the 'latent' content of a popular film. Using a tracking algorithm, the middlebrow  romance "Girl with a Pearl Earring" is reduced to its most crucial token – Scarlett Johanssen's scarlet lips.  Extracting this one signifier, Scarlett's famous mouth, wrenches the true subject of the movie – her lips, and their erotic juxtapositions – out of the extravagant context of costume drama in which it is cushioned. The entire film, both sonically and visually, is thus in some way squeezed through it's primary feature, the point to which our eyes are drawn: the inaccessible eroticism of the star.


Spectral City (2007)

Spectral City is an audio installation designed for a public space.  Every city has a chord underlying it, inaudible to us beneath the short-term activity of daily life: this installation listens to its surroundings, extracts and amplifies this chord, and plays it back.  This secret sound is permeating us unconsciously every day. The intent of this piece is to bring it to the fore, revealing the hidden sonic architecture of the city.
