  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  dithering 
 
  A  technique  used  in  {computer  graphics}  to  create  additional 
  colors  and  shades  from  an  existing  {palette}  by  interspersing 
  {pixel}s  of  different  colours.  On  a  {monochrome}  display, 
  areas  of  grey  are  created  by  varying  the  proportion  of  black 
  and  white  pixels.  In  color  displays,  colors  and  textures  are 
  created  by  varying  the  proportions  of  existing  colors.  The 
  different  colours  can  either  be  distributed  randomly  or 
  regularly.  The  higher  the  {resolution}  of  the  display,  the 
  smoother  the  dithered  colour  will  appear  to  the  eye. 
 
  Dithering  is  used  to  create  patterns  for  use  as  backgrounds, 
  fills  and  shading,  as  well  as  for  creating  {halftones}  for 
  printing.  It  is  also  used  in  {anti-aliasing}  in  order  to  make 
  jagged  lines  appear  smoother  on  screen.
