“Blue Spheres” is an exploration into the nature light—how it’s created, reflected and refracted. In an attempt to capture an inner experience within the mind, I strive to create objects which are comprised of only light. In this image, the central yellow light has no underlying physical substance, it is simply a quantum of pure existence. The same is true of the beams projecting from the interior, they are objects of colored light. The substance of each sphere is transparency, plus a tint of blueness. What we see in the spheres are reflections and refractions of light passing through.
