Invisible Sun

I wanted to have some encoding in a tattoo I'm getting, so I wrote a little program to help me with that.

Usage

invisible-sun [OPTIONS] <WORD>

Arguments:
  <WORD>  A string made up ONLY of uppercase ASCII characters and spaces

  -v, --variation <VARIATION>  How much lines vary in length from 'A' to 'Z' [default: 0.5]
