    Abstract: Disclosed is an apparatus and method for making temporary colorful birefringent displays. In its preferred embodiment, cellophane 104 is laminated between self-adherent vinyl sheets 108 with non-water soluble adhesive 112 and desired shapes 212 are cut therefrom. Plane polarizing filter 213 is similarly laminated between sheets of self-adherent vinyl 214. One of the polarizer laminations is adhered to a gloss surface such as a window 217. Shapes 212 cut from the cellophane-vinyl laminations are adhered to the polarizer lamination 215. Colors created by the polarized light passing through the birefringent cellophane laminations 100 are viewed through a polarizing analyzer 230 which can be a second lamination of polarizer between self-adherent vinyl sheets and placed over the completed design, or through analyzers held separately from the design such as polarized glasses 218 or hand held viewers 222, 230. Transmissive 214 and reflective 304 and transflective 604 types are disclosed.
