spectral transmission: iteration 1 - laser transmitter / solar cell receiver. "playing" the lights.

scenario: any darkened space. in this example, several lasers are projected through hand-made diffraction gratings,
resulting in a room-full of light. two of the lasers in particular are attached to a transformer through which audio signals
are being directed - one is music; the other, spoken word. the light from these lasers is apparent to the viewer because
they can see very clearly those points of light which pulse, brighter and darker. when a solar cell does not hit a beam directly,
the participant sees light but hears nothing. when a cell is pointed towards one of the "talking" lights, the visual experience
merges with audio, as the transmission is decoded.


fig. 1, 2: example of patterns surrounding the room, all walls, floor and ceiling. complex yet discernable patterns of laser spots are softened by diffused spotlights.


fig. 3,4: as one enters the space, they will be instructed to place the optical receiver device (a solar cell attached to headphones) in the path of any spot that appears
to be pulsing. this will reveal the sound encapsulated in the light, as it plays through the earphone. each person will have one solar cell "channel" per hand and ear,
and each laser beam will be transmitting a different sound. therefore, the participant would feel compelled to explore the space, attempting to uncover the messages
with their eyes (to find them), their hands (to focus on a sound) and finally, their ears.



fig. 4, 5: as the participant explores the space looking for messages, they will be immersed in light from every direction; pictured above is a prototype solar cell encapsulated
in a protective focusing case, and attached to a simple piezoelectric earphone. a more substantial model will be fabricated for the final installation.

fig. 6, 7: first prototype for laser transmission system: circuitry(above) and encased in a project box. the final installation will consist of more lasers
(hence , more sound sources) and higher-fidelity receivers.
