ABSTRACT:
A method of randomizing elements into a random pattern on a surface so the random pattern of elements substantially entirely consumes a region of the surface includes choosing an overlap distance and creating an initial pattern of elements that substantially entirely consumes a region of the surface, wherein neighboring elements overlap by the overlap distance. The method also includes choosing a maximum displacement distance, and displacing the elements by random displacement distances from their positions in the initial pattern, the random displacement distances being less than the maximum displacement distance. Moreover, a signed difference in displacement between two neighboring elements is not greater than the overlap distance. An apparatus including the elements is also disclosed.
