Certain example embodiments relate to making use of the difference in visually perceivable spectra as between humans and birds to create at least pseudo-random and generally non-repeating patterns that help deter birds from colliding with building facades and other transparent barriers, techniques for creating such patterns, articles including such patterns, and methods of making such articles. The patterns include design elements or areas of a UV-reflective material that is visible to birds and may or may not be easily perceivable to humans. The patterns may be created in accordance with a plurality of design rules embodied in a computer-implemented algorithm. Design rules relate to position, rotation, and/or size randomness of the design elements included in the pattern. Execution of the algorithm defines the pattern. Once the pattern is defined, the transparent substrate can have the pattern applied thereto via any suitable manufacturing technique.
