Artistic Mosaic Tile Giraffe Mural with the multicolored drops cascade to the ground, where they turn into another kind of mosaic called glass mosaic. The large yellow and orange neck on each side of the doorway are ancient symbols. They have been used in New Mexican painting, sculpture, furniture, and architecture for hundreds of years, and these traditions continue in the present. In this mosaic, they are a symbol of blossoming life after it rains.
