       Fractal Art Gallery Parameter Studies  | 
    
All twelve of these images are Julia sets 
  of the equation f(z) = (1 + ic) * cos z . 
  The imaginary component of the complex constant c has been adjusted from 
  image to image to demonstrate what dramatic changes are produced in the 
  fractal pattern by altering this parameter quite subtly.
