the first North American architects to use computers to assist in the design process. His curvilinear designs reflect the landscape around them, so that people making use of the building can retain a sense of the surrounding land. He found that the use of computerized design would fit best for his unusual designs and the use of shapes. He also found 3D programs very useful for laying out the exact dimensions of buildings. In 1993, he was hired by the Smithsonian Institution as the Primary Design Architect for the National Museum of the American Indian (NMAI). The NMAI is currently situated on the National Mall in Washington, D.C., and is directly across from the Capitol of the United States of America. After contractual disputes, Cardinal was removed from the project in 1998 before it was completed, but he continued to provide input into the building's design. In 2008, his firm was hired by the Kirkland Foundation to design a museum/convention center in Union City, Tenn. The Discovery Park of America was to be a unique structure housing a multi level museum with artifacts from across the nation as well as provide a place for large conventions/meetings for the community. Early in 2009 the firm's contract was terminated with the owner, and all construction activity was halted, due to undisclosed differences between the two parties. Architectural style and philosophy Throughout his early years, Douglas Cardinal was dealing with racism and societal ideas of conformity for both his lifestyle and architecture. Only in his years in Texas he started to fully embrace his indigenous heritage and learn more about it. In 1970s Cardinal developed his trademark architectural style with organic curvilinear forms. In those years he started wearing native clothes and necklaces, as well as becoming an advocate for indigenous rights. This spiritual connection with his native culture affected and influenced his work and unique architectural approach. Many philosophical ideas of indigenous history include its respect and sensibility towards nature, humans' inseparable relationship with the environment and land. These concepts resulted in his use of natural materials, organic shapes, soil and sun studies, as well as creating spaces that move people spiritually and make them appreciative of their surroundings. The native philosophy is also very contrasting from the Western civilization worldview due to its use of time. It is appreciative of resilience of nature and its ability to withstand hard conditions.
