The image presents a simple yet effective visual metaphor for the concept of heart. On the left side, there is a single footprint with the caption "Heart is combined with foot - will cut out." This suggests that the heart is combined with the foot, and the result is a footprint. On the right side, there are two footprints, each with a heart inside, symbolizing that the footprints are now heart-shaped. The caption "Heart is layered on top of foot - will change color of the foot and the heart" implies that the footprints have been transformed into heart shapes, and this change is reflected in both the footprints and the hearts. The image effectively communicates the idea that the heart and foot are interconnected, and the transformation of the footprints into heart shapes represents a change in perspective or understanding.
