A series based upon the truth tables of the basic one and two input logic functions: not, and, or, nand, nor, xor and xnor. Here the logic state is represented by colour instead of the more usual 0 or 1, and the circle and square motifs are used to indicate the influence each input has on the next state of the output.
the logic and influence of circle and square by revad david riley (will be sized to suit the chosen installation space, 2009)
The series can be installed to any size installation space, from a postcard to an entire gallery or the side of a building. There are eight images in all and eight basic components. These can be presented as a complete series, individually, or broken down into individual components.
