Abstract: One or more transparent or translucent sheets of cellophane are folded and cuts are made to create symmetric patterns and designs. The cellophane creates diffraction, refraction, interference, and reflection pattern of light that become strikingly visible when viewed under polarized light. The cellophane patterns and designs are placed on top of one another such that the holes in the overlapping sheets cause a variation in the path of light traveling through the layers of the cellophane, creating beautiful and varied optical patterns of light that change with the placement of the layers of cellophane and with variation of the angle of polarized light for a kaleidoscope effect. The cellophane is viewed against the backdrop of a blue sky to provide a source of polarized light. Placing the cellophane on glossy black cardboard brings out the prismatic colors created by light refraction and reflection.
