A method of forming an article, wherein the method comprises: providing a substrate and a coating comprising pigment flakes that include magnetic or magnetizable material, supported by the substrate, aligning the pigment flakes with a magnet so as to form a pattern wherein the pigment flakes are aligned along magnetic field lines in a plurality of cross-sections (200, 201, 202), wherein each cross-section (200, 201, 202) is normal to the substrate and normal to an imaginary straight line connecting first and second points on the surface of the substrate 100), curing the coating with aligned pigment flakes, wherein the method of forming the article is characterized in that (i) the magnet includes a shape of a square, wherein the magnet is magnetized along a diagonal of the square, or aligning the pigment flakes with a magnet having a shape of a diamond, wherein the magnet is magnetized along a diagonal of the diamond, and when light is incident upon the pigment flakes from a light source, light reflected from the pattern forms a bright image which appears to gradually change its shape and move from one side of the continuous imaginary line to another side of the imaginary straight line when the substrate is tilted with respect to the light source, or (ii) the magnet includes at least three magnets connected by brackets so as to form a zigzag, or aligning the pigment flakes with a stack of flexible magnets bended within brackets so as to form the zigzag or wave, and wherein, when light is incident upon the pigment flakes from a light source, light reflected from the pattern forms a bright zigzag or wave which appears to move when the substrate is tilted with respect to the light source. providing a substrate and a coating comprising pigment flakes that include magnetic or magnetizable material, supported by the substrate, aligning the pigment flakes with a magnet so as to form a pattern wherein the pigment flakes are aligned along magnetic field lines in a plurality of cross-sections (200, 201, 202), wherein each cross-section (200, 201, 202) is normal to the substrate and normal to an imaginary straight line connecting first and second points on the surface of the substrate 100), curing the coating with aligned pigment flakes, wherein the method of forming the article is characterized in that (i) the magnet includes a shape of a square, wherein the magnet is magnetized along a diagonal of the square, or aligning the pigment flakes with a magnet having a shape of a diamond, wherein the magnet is magnetized along a diagonal of the diamond, and when light is incident upon the pigment flakes from a light source, light reflected from the pattern forms a bright image which appears to gradually change its shape and move from one side of the continuous imaginary line to another side of the imaginary straight line when the substrate is tilted with respect to the light source, or (ii) the magnet includes at least three magnets connected by brackets so as to form a zigzag, or aligning the pigment flakes with a stack of flexible magnets bended within brackets so as to form the zigzag or wave, and (i) the magnet includes a shape of a square, wherein the magnet is magnetized along a diagonal of the square, or aligning the pigment flakes with a magnet having a shape of a diamond, wherein the magnet is magnetized along a diagonal of the diamond, and when light is incident upon the pigment flakes from a light source, light reflected from the pattern forms a bright image which appears to gradually change its shape and move from one side of the continuous imaginary line to another side of the imaginary straight line when the substrate is tilted with respect to the light source, or (ii) the magnet includes at least three magnets connected by brackets so as to form a zigzag, or aligning the pigment flakes with a stack of flexible magnets bended within brackets so as to form the zigzag or wave, and wherein, when light is incident upon the pigment flakes from a light source, light reflected from the pattern forms a bright zigzag or wave which appears to move when the substrate is tilted with respect to the light source.
