Fabricating Light - pixel field rendering



Attached are two images showing the assembly with the updated image. The first shows the pixels rotated in relation to the lighting source, the second shows the same pixels with the light source on the other side of the room, if we were to put two contrasting lights on it and switch between the two.

We're considering using two projectors for the lighting since they can be mounted where we need them and then we can set up black/white movies to play and the light will switch between the two. Since we can basically create the lighting effects however we want in aftereffects, we'll have a lot of freedom to do our own on-off transitions between the two projectors.

We chose to use a more figurative image as opposed to the previous one which was more abstract. We felt that since the main thrust of the project was to convey how the light is creating the image on the board, that might be lost if the image is something that becomes simply a texture of rotated pixels. By creating a more recognizable image, the viewer isn't trying to discern the image and can focus on how the system functions.

This demonstration in its current iteration functions as static representation of a responsive system. The individual pixels respond to the external stimuli of a singular light source, each altering the orientation of its base and angle of its face according to the intensity of illumination that it receives. Acting in concert, the pixels depict the image of two Native American masks from the Pacific Northwest. While the pedigree is inconsequential, the mask is pertinent to the overarching concept behind the system. The mask represents a crystallization of the human face in a specific moment in time. Composed of a complex network of nerves and musculature, the human face is perhaps the most evolved responsive topological system occurring in nature as it constantly adapts to changing environmental and emotional stimuli. It is the interface through which all human interaction is conducted. Depending upon the stimuli, the face responds accordingly and produces the desired result. Likewise, the pixels respond to the light source to generate the image.
