The interior of this piece is composed of filter glass, dichroic glass, and tinted adhesive, as well as leaded and non-leaded crystal. All of these elements combine to create an accented blue wonderland. After it's fashioned into a cube, it's deconstructed and reassembled with an optical crystal square that allows one's vision to make the transition from one side to the other. Lenses are carved into the exterior of the piece, which allows one to have even more vistas to marvel at. It measures 11x11x6.
