... this is the next joke I want to publish for the 48sx:

Display 4 colors (grey, of course) at one time!!!!

As you can see, the display routine works fine as long as there
is not much "grey" on the screen. But as soon as there are larger
regions filled with "grey", the LCD display shows some nasty 
stripes... I really do not know why.

Maybe there are some LCD-experts out there who can tell me the
reason for this strange behaviour of the LCD display.

I will not proceed in trying to force 4 colors on the 48sx-screen
as long as these problems do not have an explanation.

now enjoy the demo...

PPS: The 4-color-display does not take much CPU-time. It's only a
     joke, anyway.

PPPS: The syntax of GVIEW.o is       GROB1 GROB2 #x #y GVIEW.o
      where GROB1 and GROB2 are the bitplanes which have to be
      >= (131+#x)*(56+#y) pixel.
