A grid employs dynamic and adjustable grid lines that communicates with a transmitting object and/or a receiving object. The grid lines may be but not limited to liner, crosshatched or pinwheel shaped. The grid may switch between opaque and translucent and the grid lines may target, calibrate to and track an object either transmitting or receiving. The grid may be employed as a filter or a privacy screen on a computer screen for instance. The grid lines are angled to match an angle of a user's position with respect to the grid.
