```
### Arch Linux
Lavat is also available on the AUR [here](https://aur.archlinux.org/packages/lavat-git). Install it with your favourite AUR-helper or manually.

$ paru -S lavat-git
```
## Usage
```
Usage: lavaterm [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`
![demo 1](https://github.com/AngelJumbo/lavat/blob/demo/demo/1.gif?raw=true)
`lavat -c cyan -R 4 -b 20 -r 2`
![demo 2](https://github.com/AngelJumbo/lavat/blob/demo/demo/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 terminal color scheme.)
