This tile is based on another ValenTangle 2018 challenge, specifically for Day 11.
We were to use any fragment, but include or incorporate hearts in it. I chose T7, but I modified the shape to make it half of a heart. Then, I rotated the orientation for half of the grid. This created full hearts across two different grid squares. Then I colored in the sections where the sides of the hearts overlapped, creating the pinwheel effect.
