ColorWave

Creates a color-cycling wave of characters in the terminal. All-in-all pretty useless.

Add this line to your application's Gemfile:

gem 'color_wave'

And then execute:

$ bundle

Or install it yourself as:

$ gem install color_wave

You can run it from the command line with or without some options:

$ color_wave --lines 20 --cycles 3 --speed 10.0

The above values are the defaults.

• --lines - the height of the wave in terminal lines
• --cycles - how many cycles of the wave will be drawn
• --speed - used as the divisor of the delay time between drawing loops; use higher values for faster redrawing
• --help - show usage information

You can use it in Ruby too:

require 'color_wave'

ColorWave.new(lines: 10, cycles: 2, speed: 1, colors: %w( ff0000 00ff00 0000ff ), chars: %w( _ / ^ \ )).run

The speed option is used as the divisor to a BASE_SLEEP_TIME constant so higher speeds will redraw the wave more quickly. The colors and chars options specify the colors and characters to be cycled through when drawing the wave.

Ctrl-C will stop it once it's running.
