Yep. Try this out:

class Display
  def zoom(i)
    puts "Zooming to #{i}"
  end
end

class AppWindow
  def initialize()
    @display = Display.new
  end

  def method_missing(method, *args)
    case method.id2name
    when /menu_zoom_(\d+)_activate/
      @display.zoom($1.to_i)
    else
      puts "Unknown method: #{method}"
    end
  end
end

if $0 == __FILE__
  app = AppWindow.new
  app.menu_zoom_100_activate
  app.menu_zoom_250_activate
  app.menu_zoom_500_activate
  app.blah
end
