Abstract
Disclosed is a toy comprising polarizing filters and birefringent film cut into shapes used to make temporary colorful birefringent designs. The birefringent film (or, alternatively, the polarizing filter) is coated with non-water soluble, non-hygroscopic low-tack or ultra-low-tack adhesive so that changeable designs can be assembled on the polarizing filter and viewed through polarized spectacles or a polarizing filter. The polarizing filters are retained in rings that can be nested and rotated in relation to each other, or movably attached to each other with magnetic attachments. An embodiment is also disclosed which makes use of the polarized light emitted from certain LCD display devices so that they can be used as a work surface to make changeable birefringent designs. Such an implementation may also use applications executed by or stored on the device to provide design outlines.
