Glitter, at least a portion of which comprises color shifting film. The glitter is useful in any of a variety of ways, including in loose form, attached to the surface of a substrate, in a dispersible combination, or present in a matrix material ranging, for example, from liquids, such as water and alcohols, to gels, such as silicone and glycerol, to hard, rigid materials such as plastics, particle board, and fiberglass. Examples of other matrix materials include putties or molding clays, rubbers, and adhesives.

1. Glitter particles comprising film comprising alternating layers of at least a first and second polymeric material, wherein at least one of said first or second polymeric materials is birefringent, wherein the difference in indices of refraction of said first and second polymeric materials for visible light polarized along first and second axes in the plane of the layers is at least about 0.05, and wherein the difference in indices of refraction of said first and second polymeric materials for visible light polarized along a third axis mutually orthogonal to said first and second axes is less than about 0.05.
