title: Ruby language cheatsheet/poster/reference/overview?
body: <p>I am a visual kind of guy and would like to know if there is somewhere a nice big overview of Ruby. You know, like a <strong>reference poster</strong>, <em>with object hierarchy</em>, most common methods, etc, all in color, layed out nice and clearly... </p>
  
  <p>To a beginner like me would this would be awesome... </p>
  
  <p>Is there something like that out there that you use or have stumbled upon?</p>
