1. A system for creating color effects using extrudable material, the system comprising:
a) a first extruder for providing a flow of a first viscous material of a first color;
b) a second extruder for providing a flow of a second viscous material of a second color different from the first color;
c) a feed block for combining the flow of the first viscous material and the flow of the second viscous material to form a stream of combined viscous material, the stream comprising a first band of the first color and a second band of the second color, the second band being adjacent to the first band;
d) a dynamic mixer for applying a dividing, overturning and combining motion to the stream of combined viscous material to partially mix the first viscous material and the second viscous material, such that upon exiting the dynamic mixer, the first material of the first color and the second material of the second color form a color pattern in the stream of combined viscous material, wherein the dynamic mixer has elements configured for acquiring a specific radial orientation in a range of radial orientations;
e) an electronic controller in communication with the dynamic mixer, the electronic controller being configured for varying the specific radial orientation of the elements of the dynamic mixer by performing clockwise and counter-clockwise rotations of the elements of the dynamic mixer during the applying of the dividing, overturning and combining motion to the stream of combined viscous material to cause variations in the color pattern in the stream of combined viscous material to form an extruded material having a surface that presents color gradation effects having an undulating color pattern oriented along a longitudinal extent of the extruded material.
