## 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)
  -k <COLOR>          Set the color of the rim if there is one. Available colours: red, blue, yellow, green, cyan and magenta.
                      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
                      Only ascii symbols are supported for now, wide/unicode characters may appear broken.
  -C                  Retain the entire lava inside the terminal.
                      It may not work well with a lot of balls or with a bigger radius than the default one.
  -h                  Print help.
```

## Demo

`lavat -c red -R 1`

![demo 1](https://github.com/AngelJumbo/demos/blob/main/lavat/1.gif?raw=true)


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

![demo 2](https://github.com/AngelJumbo/demos/blob/main/lavat/2.gif?raw=true)

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.)
