Projects a grid or line raster onto an image. The grid gets distorted by the image's color, luminance or saturations channel. Gives some nice op-art effects if you switch off the image itself (Blend Mode 1) and choose some low frequencies.Note: Minimumk Frequency should always be smaller than MAximum Frequency. If you use random variations you will have to correct this manually.
