It was exciting to participate in the first exhibition in 1986 when the land was barely reclaimed from an urban dump, and it is doubly significant to be part of the 10th anniversary exhibition. Socrates Park has continued to grow and affect the lives of so many people during its 10 years of life. The Cloak of Motion is part of a series of rotational, planetoid works that began during my residency at La vie des Formes in 1991. This work is a diagram of matter in motion as well as an attempt to map the structure of the universe. It reflects my excitement with the scientific contraptions of 17th century natural philosophers and our continuing attempt to understand the physical world by building devices to conjure the territory of our investigation.
