Neither "head -100 /bin/true" nor the above work.  /bin/true spits out a =
bunch of binary data that gnuplot can't interpret.  /dev/zero creates an =
empty file.

This works.  (We can't use this in demo scripts.  Right?)

Good thing to consider, but the idea is to keep the two independent.  The=
 1D/2D p.d.f. is the function plot, the random points to plot are a "data=
 file".  If one changes his or her prespective, we might say that using r=
and(0) tied to the grid sampling is the kluge.  I mean, that isn't exactl=
y a solid concept in terms of application... unless say the way Ethan is =
using it in his variable_rgb.dem example where the random part is actuall=
y another dimension (i.e., dot size and/or color).
