OPTIONS:

                    Besides those colors the default one is the normal foreground of your terminal.

  -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

`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.)
