title: How to make a "matrix" for puzzle bubble?
body: <p>Hey guys, I'm trying to make a puzzle bubble clone but I'm stumped on how to handle the background stuff. Mostly with the fact that the lines don't match up (i.e: instead of a bubble having another no top of it, one on the upper-left and one on the upper-right, it has one on the upper left and one on the upper right <a href="http://dl.dropbox.com/u/680263/puzzle_bobble_2.jpg" rel="nofollow">http://dl.dropbox.com/u/680263/puzzle_bobble_2.jpg</a>) and how to determine which bubbles pop when I make shot (and which fall) without making a brute-force algorithm that would make my i7 cry.</p>
  
  <p>Can anyone give some sugestions on how to handle this?</p>
