Concept: Our concept evolved from numerous ideas about the interaction between people and pixels. Initially we were intending to use animation (and the construction of an animation based off of user input) as a means to show the idea of optics. Essentially, human eyes are unable to process minute changes in quickly moving images as distinctly separate moments. Because of this, while we may not be aware of each individual frame, it is through the quick progression of these images in which the illusion of movement can be made. As we did not have the processing power to rapidly change each individual LED at the same time, we decided to change our concept to reflect more on the idea of images as a combination of Red, Green, and Blue lights. As every color is created from these three essential primaries, we began to think about their role in the construction of not only moving images, but still images as well. In attempting to create different colors using just three LEDs, we chose to use Pulse Width Modulation in order to mimic an analog output with a digital source. Unfortunately, the arduino boards used were unable to display all of these minute modulations at the same time; the output instead was more of a sequence of LED displays rather than a cohesive combination. Interested by this idea of speed in terms of computer processing and the similarities found in human optics, we wanted to explore the ways in which the two interacted--as well as how people interacted with actually seeing the changes, which are typically unnoticeable. We included two potentiometers as means for people to adjust the speed in which the pixels were cycling, but never allowing them to reach a speed in which a complete image would be formed. Through this, we intended for our viewers to test their patience and tolerance when viewing a heavily deconstructed image. By never allowing a full image to be formed, the viewer is then forced to think more about the idea of deconstruction rather than the notion of a subject-oriented image. While we chose the form of a television to display the screen, we made it clear to the viewer that this was a small grid of large pixels, enlarged to a size in which their role became integral in the interaction with the piece. We hope people walk away from this with a better appreciation for a display's rudimentary components, while still realizing the complexity of creating a full, clear image.
