rain — animated
rain is modeled after the VAX/VMS program
of the same name.
To obtain the proper effect, the
may be used to specify a delay in milliseconds between each update.
Reasonable values are around 20–200. The default is based on the
terminal speed, computed via the following formula:
delay = speed / 9600 - 1
As with any curses(3) program,
TERM environment variable must be set (and
exported) to the type of the terminal being used.
