Carroll’s wall constructions focus on three-dimensional shapes coming out of a flat plane. From the square, shapes are extended and juxtaposed against each other, resulting in the feeling of movement, either separation or convergence. The subtle movement of the shape lets light and shadow become a part of the piece. As in nature, nothing stays still. The study of plate tectonics shows even the earth is constantly shifting, pulling apart and colliding together, in the creation of new places. Forms that appear solid and constant are actually moving, albeit at a geologic pace.
