Based on the the drawille library for Python, this library allows the developer to draw using Unicode braille symbols in the terminal.
The library extends drawille to support RGB colors in the terminal. It doesn't attempt to degrade gracefully to terminals that don't support RGB. This library is very much a work in progress. If there's functionality in it that you wish to see, please feel free to fork or submit a pull request.
require "drawille-cr" c = Drawille::Canvas.new (0..180).each do |x| c.set(x, (10 + Math.sin(x * 2 / Math::PI * 10) * 10).to_i32) end print c.render
