I research the precedent which is Richard Serra. He used the massive metal plate to create the minimalist, abstract sculpture. Inspired me is Richard Serra think sculpture not just a beautiful isolate object, it should connect with space and audience.
Like tilted arc, this giant sculpture put on the federal, people first-time noticed this space which people walk every day, increased interaction with area and building. And the slightly mental plate give an unstable sense, effect people feeling constantly.
Richard Serra used a simple curve, to let people notice this space again, have the new experience.
This is inspired me. Also the arc often used in Richard Serra works, when people walk in, the mental feeling changed following with arc changing. To motive people experience.
