I hooked my Ruby-based library (which uses the Gang of Four strategy pattern to generate visuals) up to Ruby-Processing, with excellent results:

(Copy-paste the links to your address bar; my board permissions don't let me post links yet.)

It was pretty easy, too - the entire code is below.

Code:

require 'rubygems'
require 'ruby-processing'
require 'rubyonacid/factories/example'

class Sketch < Processing::App

  def setup
    @f = RubyOnAcid::ExampleFactory.new
    @resetter = RubyOnAcid::SkipFactory.new(0.9999)
    background 0
    smooth
    ellipse_mode CENTER
  end
  def draw
    100.times do
      fill(
        @f.get(:red, :max => 255),
        @f.get(:green, :max => 255),
        @f.get(:blue, :max => 255),
        @f.get(:alpha, :max => 255)
      )
      no_stroke
      ellipse(
        @f.get(:x, :max => width),
        @f.get(:y, :max => height),
        @f.get(:width, :max => 300),
        @f.get(:height, :max => 300)
      )
      @f.reset_assignments if @resetter.boolean(:reset)
    end
  end
  
end

Processing::SKETCH_PATH = ""

Sketch.new :title => "Ruby On Acid", :width => 1024, :height => 768, :full_screen => true
 

Ensure JRuby is installed (I haven't been able to get external libraries working with Ruby-Processing's included rp5 tool).  Then run "sudo jgem install ruby-processing rubyonacid" to install the JRuby gems.  Save the above code to "acid.rb" and type "jruby acid.rb" to run it.

This can definitely be taken a lot further - I haven't had a chance to play with most of Processing's capabilities.  If anyone on the board tries it out and encounters trouble, drop me a line and I'll see if I can help.
