Vasa Mihich's cast acrylic sculptures, made from clear and colored sheets of acrylic plastic laminated with polymerized glue, create visually complex structural planes with ever-changing appearances. The sculptures are based in explorations of optics and perception, the behavior and properties of light. Enveloping clear with colored plastic or vice versa, Mihich creates optical illusions of transparency or color: what may be perceived as solid color may be mostly clear plastic -- sandwiching a thin slice of color -- and what is seen as transparent may be a reflection.

Optics and perception are also at the core of Vasa Mihich's paintings, many of which explore possibilities of "fighting the grid." The grid is deconstructed in seemingly endless variations, for example through the use of lines in different hues that may have the same value of grey and are offset with white or black lines of varying thickness that override the color.
