Google code is high above me - can anybody help a Javascript n00b?
<p>ok, I have been looking into google maps for 2 days now when I found this beautiful sample from google engineer Roman Nurik: shit! only 1 link allowed, lol.</p>

<p>The source code is available here: <a href="http://code.google.com/p/googleio2009-map/" rel="nofollow">link text</a></p>

<p>I am a casual developer at beginners level in javascript (usually C,C++C#) and I would be very greatful if somebody would explain the main cornerstones and nuts&amp;bolts of this code to me...</p>

<p>I have some concrete questions which I would point out but of course I am eager to find out the answers by myself - just need a short stimulus... :)</p>

<p>Thank you!</p>
