I was so obsessed with pushing further with this that I played a little more yesterday after work and some more this morning. Here is how far I am now: 13 rows! Due to space limitations, I'm not sure how much further I can go. I'll try for 14 or more when I have time. Until then, here is a video of the build: http://www.youtube.com/watch?v=_QCHq7OoF_8
I know I'm nit-picking, but... Can someone update the initial post to indicate that I completed 13 rows (not "5")? *update* Thanks Amnesia
