How does art come into being? Out of volume, motion, spaces carved out within the surrounding space, the universe. Out of different masses, tight, heavy and middling—achieved by variations of size or color. … [Out of] spaces and volumes, created by the slightest opposition to their mass, or penetrated by vectors, traversed by movement.

—Alexander Calder
