The Brush series is an attempt to model a brush stroke as a collection of similarly coloured bristles, and to both further identify methods of assigning a brush stroke path, and methods of modifying the brush strokes based on the position on the screen.  To model the brush I had a brush colour, and n bristles, each with a colour that varied by a small random amount from the colour of the brush.  These bristles were randomly located within the circular confines of the brush.
