The present invention provides methods and systems related to arranging objects (e.g., circles, dots and other shapes) in images and graphics to convey a machine-readable signal. One claim recites a method including: integrating a plurality of objects in an image or graphic, the objects being arranged in a pattern that is machine-readable by a programmed computer processor, the plurality of objects being integrated in the image or graphic so that the pattern is hidden in the image or graphic through cooperation with design elements of the image or graphic; and providing a visible structure for aiding in machine-reading of the pattern by the programmed computer processor. Of course, other combinations are provided and claimed as well.
