A fishing line comprises an outer surface having at least one array of shaped features therein and having an advancing contact angle with deionized water of at least about 115&#xb0;. The array comprises a plurality of discrete shaped features spaced equidistantly along a longitudinal axis of the fishing line. The shaped features are from about 0.005 to about 0.02 inches across in their broadest dimension.

Lines having shaped surface and method of making

Projection screen assemblies include one or more birefringent retarding layers and one or more polarizing layers. The retarding and polarizing layers reduce the unwanted reflection of ambient and image light. One embodiment of a screen assembly includes a dispersing layer having an input side to receive light from a light source and a first retarding layer disposed to alter the polarization of the light transmitted by the dispersing film. A first polarizer substantially transmits light received from the first retarding layer in a first polarization state and absorbs light received from the first retarding layer in a second polarization state orthogonal to the first polarization state.
