The coaster is like a 3d carpet with hundreds of heart facets on it. On the top view, it's just a square grid, while with the shift of the view angle, it could provide with various 3D wavy appearance in a grid. It is a work between 2d and 3d, and is a good combination of romance and 3D visual. The coaster is sized 10x10x0.7cm, please don't hesitate to contact me if you want other size.
