The BCC Light Sweep filter creates a linear beam of light that sweeps across your image. The filter is physically modeled after a light that is infinitely far away. The light is infinitely wide in one direction, and falls off in the other. Light Sweep also has some very useful edge detection and edge lighting features.
The built in PixelChooser, with integrated mocha planar tracking allows for greater control over which areas of the image the filter should affect.
