Cortical Circuitboard features a stylized array of cortical neurons that are arranged into the layered structure of the cerebral cortex. Incorporating aesthetic motifs drawn from circuitboard design into the neural landscape, it draws parallels between the chaos of a biological brain and the order of an electronic one.
This piece features the first example of Dr. Edwards’ animation algorithm. Using visual information built into the design, Dr. Edwards wrote a program that calculates the precise angle necessary at any coordinate on the microetching to reflect light to the viewer standing at a given position. This allows light to reflect off of the surface in specific ways, giving the artists the ability to depict animations within each neuron. As the viewer walks past the microetching the neurons fire action potentials, creating a finished piece whose circuit dynamics represent the actual firing patterns found within the cerebral cortex.
Microetchings are handmade lithographs that manipulate light on a microscopic scale to control the reflectivity of metallic surfaces in precise ways. These techniques were invented by Dr. Greg Dunn and his colleague Dr. Brian Edwards in order to change the way in which the viewer experiences a painting. Please note that these microetchings are designed to evolve based on the moving perspective of the viewer and are impossible to capture in still images.
