Hopeless romantics (as all golfers are) may enjoy reading Bridgestone’s patent USPN 7,018,308 (http://www.pat2pdf.org/patents/pat7018308.pdf). The ‘308 patent discloses and claims heart shaped dimples.

The shape, surrounded by the edge, of the dimple is not limited to a circular shape shown in FIGS. 2 and 3 but may be a non-circular shape, examples of which include a polygonal shape such as a triangular, quadrilateral, or hexagonal shape, an elliptic or oval shape, a petal shape, a heart shape, a star shape, a dewdrop shape, and a combination thereof (FIG. 7). If the edge of the dimple is formed into such a non-circular shape in a plan view, the bottom portion of the dimple may be similarly formed into a non-circular shape in a plan view.

11. A golf ball according to claim 9, wherein dimple shapes of said multiplicity of dimples in a plan view includes at least one of a triangular shape, a quadrilateral shape, a hexagonal shape, an elliptic shape, an oval shape, a petal shape, a heart shape, a star shape, a dewdrop shape, and a combination thereof.

Figure 7 is reproduced below. Can you find any hearts?
