SnowPlants Blanker  (Version 1.8; 16-Feb-97)
by Ingo Schmiegel

Some points are falling
from the top of the screen to the bottom.
If one point moves to a place where another point lies,
it stops moving and a new point starts falling down.

Parameters:
· Select if points are drawn during falling or not
· Colours: white, once rnd selected, cycling, copper or multicoloured
  cycle delay: delay between changes of colour (in fallen points)
· Points: Number of points used for one picture (in fallen points)
  MaxHeight: Maximum height allowed in a picture (in pixels)
  (One of the last two immediately ends the actual picture)
· Cycle: Const/Max aperture of falling direction (0:always vertical)
  Aperture: The lesser -> the steeper do the points fall
· Pixel delay: delay between each pixel movement
· Picture delay: delay before beginning a new picture (in seconds)

Note:
· A big display results in slower picture building.
· More than two colours are only used, if the multicolour mode
  is active.
