Design a futuristic building in the style of Santiago Calatrava, characterized by organic, flowing forms, clean white surfaces, and dramatic structural lines. The building should integrate a Christmas theme, using red and green as accent colors through lighting, glass panels, or decorative elements. The design should subtly evoke Christmas symbols, such as abstract forms resembling Christmas trees, ornaments, or snowflakes, while maintaining Calatrava's signature modern, sculptural aesthetic. The result should be a striking, elegant structure that captures the holiday spirit through innovation and artistic architecture.
