1. A cast block for use in a wall that is configured to be built on a surface, the block comprising: a body including a top surface, an opposed bottom surface spaced from the top surface by a height of between about 1 inch and about 12 inches, the top surface being substantially planar and defining a top surface plane, the bottom surface being substantially planar and defining a bottom surface plane, and the bottom surface configured to face the surface when used in the wall, the body further including opposed first and second side surfaces, each of the first and second side surfaces extending from the top surface to the bottom surface, and a rear surface extending between the top and bottom surfaces in a first direction and also between the first and second side surfaces in a second direction; anda face portion extending frontwardly from the body, the face portion including a front surface, an upper tapered surface, and a lower tapered surface, the upper tapered surface extending between the top surface and the front surface such that a top taper angle is defined between the upper tapered surface and the top surface plane, the lower tapered surface extending between the bottom surface and the front surface such that a bottom taper angle is defined between the bottom tapered surface and the bottom surface plane, the top taper angle being selected from a range of angles between about 5 degrees and about 45 degrees, the face portion further including a top taper depth and a bottom taper depth, the top taper depth measured frontwardly from an intersection of the top surface and the upper tapered surface to the front surface, such that the top taper depth is between about ¼ inch and about 4 inches, the bottom taper depth measured frontwardly from an intersection of the lower tapered surface and the bottom surface to the front surface, such that the top taper depth is shorter than the bottom taper depth, the face portion configured to cast a shadow line that at least partially covers a cast block positioned below the cast block in the wall;wherein the body defines a length measured from the rear surface to the face portion, the height of each of the first and second side surfaces is substantially constant along the length of the respective first and second side surface; and the front surface, the upper tapered surface, and the lower tapered surface are each patterned. 2. The block of claim 1, wherein the front surface is disposed at least partially between the top surface plane and the bottom surface plane. 3. The block of claim 2, wherein the top surface plane and the bottom surface plane are substantially parallel to each other and the front surface is substantially perpendicular to the top surface plane and the bottom surface plane. 4. The block of claim 1, wherein at least one of the upper and lower tapered surfaces are at least partially nonlinear. 5. The block of claim 1, wherein at least one of the upper and lower tapered surfaces are at least partially linear. 6. The block of claim 1, wherein the top taper angle is between about 10 degrees and about 27 degrees. 7. The block of claim 1, wherein the bottom taper angle is between about 5 degrees and about 45 degrees. 8. The block of claim 1, wherein the bottom taper angle is between about 10 degrees and about 27 degrees. 9. The block of claim 1, wherein the top taper angle is greater than the bottom taper angle. 10. The block of claim 1, wherein the bottom taper angle is greater than or equal to the top taper angle. 11. The block of claim 1, wherein the height is between about 2¼ inches and about 4½ inches. 12. The block of claim 1, wherein the front surface further comprises an upper edge, a lower edge, and a front surface height defined by a distance between the upper edge and the lower edge of the front surface, and wherein the front surface height is at least 50% of the body height. 13. The block of claim 1, wherein the face portion further comprises a first side tapered surface that extends between the first side surface and the front surface. 14. The block of claim 13, wherein the face portion further comprises a second side tapered surface that extends between the second side surface and the front surface. 15. The block of claim 1, wherein the top taper depth is between about ½ inch and about 2½ inches. 16. The block of claim 1, wherein the bottom taper depth is between about ¼ inch and about 4 inches. 17. The block of claim 16, wherein the bottom taper depth is between about ½ inch and about 2½ inches. 18. The block of claim 1, wherein the opposed first and second side surfaces are parallel to each other. 19. The block of claim 1, wherein the opposed first and second side surfaces are oblique to each other. 20. The block of claim 1, wherein the top surface and the bottom surface are substantially planar and substantially parallel to each other such that the height of the body is substantially constant along the length of the body.
