This effect picks a limited number of colours to best represent the input image. The output is the image drawn using only those colours. It gives an effect similar to Posterize, but with a more intelligent choice of colours. Since the colour picking process depends on the colours in the current frame, if the colours change rapidly between frames you can have a distracting rapid change of palettes. To try and prevent this, I've included a way to damp down the speed at which the palette changes using the 'Palette Persistence' variable.
Parameters

1. Colour Count
How many colours to reduce the image to
2. Palette Persistence
How 'sticky' the palette is, with high values the palette changes very infrequently, with low values it changes rapidly
