  • illuminating the at least one light sensitive layer with the pattern revealing light using at least one light source, the pattern revealing light having a wavelength that is less than approximately 450 nm, the at least one light sensitive layer being arranged to absorb the pattern revealing light and emit a colored light in response such that the previously hidden pattern is revealed, wherein the at least one light sensitive layer, when not exposed to the pattern revealing light, is arranged to not emit the colored light;

    increasing and decreasing the intensity of the pattern revealing light repeatedly, thereby causing the intensity of the emitted colored light to also increase and decrease;
