A method of making a tiled article, the method comprising: providing a tile (24, 25) including a top surface comprising prism elements, wherein the tile (24, 25) comprises a master comprising a substrate including prism elements on a top surface thereof; forming a depression in the substrate which results in the removal of only a top peripheral portion of the substrate thereby creating a lip on a bottom or lower portion of the substrate; forming a wall on the tile (24, 25) by removing a portion of the top surface of the tile (24, 25), wherein the wall is made in the substrate by forming the depression in the substrate and wherein a reference edge corresponds to the wall, wherein the wall shares a first common edge with the top surface of the tile (24, 25); forming replicas of the tile (24, 25); forming a face on each replica by removing a portion of each replica which results in removal of the lip and exposing the reference edge such that is mateable face-to-face, and wherein the face shares a second common edge with a wall, corresponding to the wall formed on the tile (24, 25), on each replica, and a first common edge, corresponding to the first common edge of the tile (24, 25), of each replica is on an opposite side of the wall of each replica from the second common edge; and positioning the replicas such that the wall, corresponding to the wall formed on the tile (24, 25), on each replica is face-to-face with, and directly abuts another wall corresponding to the wall formed on the tile (24, 25) on an adjacent replica to thereby form a tiled article, wherein each face on each replica is at an angle (Fθ) of less than 180°from the wall as measured through the replica. providing a tile (24, 25) including a top surface comprising prism elements, wherein the tile (24, 25) comprises a master comprising a substrate including prism elements on a top surface thereof; forming a depression in the substrate which results in the removal of only a top peripheral portion of the substrate thereby creating a lip on a bottom or lower portion of the substrate; forming a wall on the tile (24, 25) by removing a portion of the top surface of the tile (24, 25), wherein the wall is made in the substrate by forming the depression in the substrate and wherein a reference edge corresponds to the wall, wherein the wall shares a first common edge with the top surface of the tile (24, 25); forming replicas of the tile (24, 25); forming a face on each replica by removing a portion of each replica which results in removal of the lip and exposing the reference edge such that is mateable face-to-face, and wherein the face shares a second common edge with a wall, corresponding to the wall formed on the tile (24, 25), on each replica, and a first common edge, corresponding to the first common edge of the tile (24, 25), of each replica is on an opposite side of the wall of each replica from the second common edge; and positioning the replicas such that the wall, corresponding to the wall formed on the tile (24, 25), on each replica is face-to-face with, and directly abuts another wall corresponding to the wall formed on the tile (24, 25) on an adjacent replica to thereby form a tiled article, wherein each face on each replica is at an angle (Fθ) of less than 180°from the wall as measured through the replica.
