Crown glass is the material from which stained glass windows were made in the infancy of our craft, year 1100 and before. Since it is made in the form of spun discs, striations and streaks of color occur in arcs. Making a stained glass window with this material involved cutting up the discs and assembling the pieces into a stained glass panel. The direction of the kinetic quality can be either random or determined. As one moves past the resulting window, or objects move past on the other side, dramatic, visual phenomena occur. The effect is similar to a carnival, fun-house mirror cut into pieces and reassembled with a focused randomness.
