In an embodiment of the present invention, the foregoing is addressed by providing a combination retaining wall structure and masonry form apparatus comprising a first block having a depending lip with non-linear edge, a second block having an upper surface with a recess presenting an inwardly facing edge, the second block being positioned with respect to a rotational axis through the first block. A zone of contact is located at the intersection of the inwardly facing edge and the outwardly facing edge, providing an area for rotation of the first block about the rotational axis of the second block. The first and second blocks forming a non-linear masonry wall structure having an upright axis, about which plural blocks may be rotated. The depending lip and recess being provided by a masonry form having a first, second, third and fourth sides, the first and second sides being removable for interchangeably configuring the first and second block.

1. A wall structure for use in landscaping and comprising: a lower block having a first front surface, a first rear surface, and opposite first side surfaces, said lower block having a substantially planar upper surface with a single recess having an open rear end and extending substantially from said first rear surface to a rear facing edge formed thereby and directed toward said first rear surface;said rear facing edge extending horizontally from said first rear surface;an upper block having a second front surface, a second rear surface, and opposite second side surfaces, said upper block having a substantially planar lower surface with a curved and convex depending lip extending from said lower surface at said second rear surface and forming a single front facing edge directed toward said second front surface, said front facing edge proximate to said second rear surface;said upper block being positioned on said lower block with said front facing edge engaged with said rear facing edge at a rearward zone of contact therebetween, said rearward zone of contact being presented at said first and second rear surfaces; andsaid upper block being set back and rotated about a rearward rotational axis of said lower block at said rearward zone of contact with said second front surface spaced angularly from said first front surface selected from a range of angles. 2. A structure as set forth in claim 1 wherein: said front facing edge is curved and convex; andsaid rear facing edge is straight. 3. A structure as set forth in claim 1 wherein said upper block has a second upper surface including a second rear facing surface directed toward said second rear surface. 4. A structure as set forth in claim 1 and including: a lower layer formed by a plurality of said lower blocks positioned in side-by-side relation;each lower block having a first front surface, the first front surfaces of adjacent blocks having a selected angular relationship to form a selected contour of said lower layer;an upper layer formed by a plurality of said upper blocks positioned in side-by-side relation on said lower layer;each of said upper blocks having a second front surface, the second front surfaces of adjacent blocks having respective angular relationships to substantially match said selected contour of lower blocks therebelow; andeach of said upper blocks engaging at least one of said lower blocks in a respective rearward zone of contact. 5. A structure as set forth in claim 4 wherein said upper blocks are staggered in relation to said lower blocks. 6. A wall structure for use in landscaping and comprising: a lower block having a first front surface, a first rear surface, and opposite first side surfaces, said lower block having a flat upper surface with a single recess having an open rear end and extending from said first rear surface to form a rear facing edge directed toward said first rear surface and spaced closer to said first rear surface than to said first front surface, said rear facing edge being straight;an upper block having a second front surface, a second rear surface, and opposite second side surfaces, said upper block having a flat lower surface with a depending lip extending from said second rear surface and forming a single front facing edge directed toward said second front surface and spaced closer to said second rear surface than to said second front surface, said front facing edge being curved and convex;said upper block being positioned on said lower block with said front facing edge engaged with said rear facing edge at a rearward zone of contact therebetween;said rearward zone of contact being presented at said first and second rear surfaces; andsaid upper block being rotated about a rearward rotational axis of said lower block with said second front surface at an angle relative to said first front surface selected from a range of angles. 7. A structure as set forth in claim 6 wherein said upper block has a second upper surface including a second rear facing surface directed toward said second rear surface. 8. A structure as set forth in claim 6 and including: a lower layer formed by a plurality of said lower blocks positioned in side-by-side relation;each lower block having a first front surface, the first front surfaces of adjacent blocks having a selected angular relationship to form a selected contour of said lower layer;an upper layer formed by a plurality of said upper blocks positioned in side-by-side relation on said lower layer;each of said upper blocks having a second front surface, the second front surfaces of adjacent blocks having respective angular relationships to substantially match said selected contour of lower blocks therebelow; andeach of said upper blocks engaging at least one of said lower blocks in a respective rearward zone of contact. 9. A structure as set forth in claim 8 wherein said upper blocks are staggered in relation to said lower blocks. 10. A wall structure for use in landscaping and comprising: a lower layer formed by a plurality of lower blocks positioned in side-by-side relation;each of said lower blocks having a first front surface, a first rear surface, and opposite first side surfaces, said lower block having a flat upper surface with a single recess having an open rear end extending from said first rear surface to form a rear facing edge directed toward said rear surface and spaced closer to said first rear surface than to said first front surface, said rear facing edge being straight, the first front surfaces of adjacent lower blocks having a selected angular relationship to form a selected contour of said lower layer;an upper layer formed by a plurality of upper blocks positioned in side-by-side relation on said lower layer;each of said upper blocks having a second front surface, a second rear surface, and opposite second side surfaces, said upper block having a flat lower surface with a depending lip extending from said second rear surface and forming a front facing edge directed toward said second front surface and spaced closer to said second rear surface than to said second front surface, said front facing edge being curved and convex, the second front surfaces of adjacent blocks having respective angular relationships to substantially match said contour of lower blocks therebelow; andeach of said upper blocks being positioned on at least one lower block with the front facing edge of the upper block engaged with said rear facing edge of said lower block at a respective rearward zone of contact therebetween, said upper block being rotated about a rearward rotational axis of said lower block with said second front surface of said upper block at an angle relative to said first front surface of said lower block, said angle being selected from a range of angles. 11.
