+## Class macro gtk_args
+
+Here's how you can use the `gtk_args` class method:
+
+```ruby
+class Game
+  gtk_args
+  attr_accessor :current_scene, :other_custom_attrs
+
+  def tick
+  end
+end
+
+$game = Game.new
+
+def tick args
+  $game.args = args
+  $game.tick
+end
+```
+
+The code above is the similar to:
+
+```ruby
+class Game
+  attr_accessor :args, :grid, :state, :inputs, :outputs, :gtk, :passes,
+                :current_scene, :other_custom_attrs
+
+  def tick
+  end
+end
+
+$game = Game.new
+
+def tick args
+  $game.args    = args
+  $game.grid    = args.grid
+  $game.state   = args.state
+  $game.outputs = args.outputs
+  $game.gtk     = args.gtk
+  $game.passes  = args.passes
+  $game.tick
+end
+```
+
+## Monkey patching the runtime
+
+You're on your own if you do this :grimacing:
+
+```ruby
+module GTK
+  class Runtime
+    alias_method :__original_tick_core__, :tick_core unless Runtime.instance_methods.include?(:__original_tick_core__)
+
+    def tick_core
+      __original_tick_core__
+      $top_level.oh @args
+      $top_level.god @args
+      $top_level.why @args
+    end
+  end
+end
+
+def tick args
+end
+
+def oh args
+end
+
+def god args
+end
+
+def why args
+end
+```
+
+## MP3's to Wav converstion script:
+
+```ruby
+`ls .`.each_line.to_a.map do |l|
+  l = l.strip
+  if l.end_with? "mp3"
+    `ffmpeg -i #{l} -acodec pcm_s16le -ar 44100 prep-#{l.split(".")[0]}.wav`
+    `ffmpeg -y -i prep-#{l.split(".")[0]}.wav -f wav -bitexact -acodec pcm_s16le -ar 44100 -ac 1 #{l.split(".")[0]}.wav`
+  end
+end
+```
