Dithering is pretty old too.  Was used by a painter with particularly
famous painting (I have it on a coffee mug) "Sunday in the Park" or some
such name. Artist's name doesn't come to mind either (just the image of
the painting).  But in any case, he used colored dots to produce other colors
through dithering -- and this was quite some time ago.  :-)
