Usage

Usage: lavat [OPTIONS]
OPTIONS:
  -c COLOR          Set color. Available colours: red, blue, yellow, green, cyan and magenta.
                    Besides those colors the default one is the normal foreground of your terminal.
  -s SPEED          Set the speed, from 1 to 5. (default 1)
  -r RADIUS         Set the radius of the metaballs, from 1 to 10. (default: 5)
  -R RIM            Set a "rim" for each metaball, sizes from 1 to 5. (default: none)
                    This option does not work with the default color
  -b NBALLS         Set the number of metaballs in the simulation, from 2 to 20. (default: 10)
  -F CHARS          Allows for a custom set of chars to be used
  -h                Print help.

Demo

lavat -c red -R 1

lavat -c cyan -R 4 -b 20 -r 2

If you send more than one character to the -F option you can have 3d-ish effect.

lavat -c blue -R2 -F @@:::::: -r10

(The colors depend on your color scheme.)
