twinkle(6) twinkle(6)
NAME
twinkle - twinkle stars on the screen
SYNOPSIS
/usr/games/twinkle [-+[ssave]] [density1] [density2]
DESCRIPTION
twinkle causes a specified density of `stars' to twinkle on
the screen. The following options are available;
- print out the present screen density (the percentage of
the screen that will be filled with stars) in the lower
left hand corner of the screen. This number will
change as stars go on and off.
+ do not `randomize' before starting. The screen starts
out completely blank and stars are added, bit by bit.
In this case the density rises beyond the specified
density, then falls to the required percentage.
s save binary density on file `save', in case you want to
see the density curve that a particular density
specification produced during the life of the show.
density
If no density is specified, density is .5 (50% of the
screen will be filled with stars).
If only density1 is given, density is 1/density1
If both density1anddensity2 are given, density is the
resultant of density1/(density1+density2).
EXAMPLE
twinkle -+ 2 6
would start from a blank screen and twinkle stars to a final
density of 2/8, or 25%. The densities would be shown in the
lower left hand corner, as a three-place decimal.
