For those who are new to the site, it may not be immediately obvious that I am the geek/nerd/worm etc component of our site.  Normally this would be of relatively little comment, but I was involved in a discussion at lunch that may change how I react with this site.

We were discussing NOLA and one of my colleagues (favored of the MSM) mentioned that in the days after Katrina he was often asked if there was a cartoon out there that could explain the floodwall failure.  He said that there never was a site he could point to.

Well, as Prof G is aware, my hobby is 3-D modelling and I had debated, in my mind, whether to post a series of about 4 pictures explaining why the flood walls failed.  I decided that it was enough off topic that I should not do so on this site.  But, since this is not a single issue, but may relate to some of the things that develop down the road, it seems only fair to poll our readers.  Particularly given that Super G has provided the rather neat option that allows a poll.  So if you can accept that I really don't undertand how to set this up - here should be the question:

[editor's note, by Super G] The poll wasn't working, but now it is. Basically I just deleted it and added it again. I'm not really sure why that worked.
