1. A method to affect natural lighting profiles in a programmable window made from a single transparent membrane, said method comprising:

  • forming a matrix comprising a plurality of pixel elements within said single transparent membrane, each of said one or more pixels being wired using a transparent conductor and capable of being independently driven to control opacity;

    setting in a programmable controller a degree of shading in at least one pixel in said matrix of pixel elements;

    receiving one or more control commands from said programmable controller, said control commands issued to control opacity of at least one pixel element in said matrix;

    in response to said one or more control commands, independently driving said at least one pixel within said single transparent membrane to set its opacity according to said degree of shading, andwherein degree of shading in each pixel element within said single transparent membrane is controlled by controlling percentage of light transmitted according to control commands issued by said programmable controller.
