   Just visited the world trade center site. The bottoms are blast proof concrete and steel bunkers! Top of One World too high to see what the heck the wrap is doing.... Lol

   Dan,
   Below is a photo from Flickr. The photographer is Chris Peters of Syracuse, N.Y. (Website: http://oracleondelhistudio.com/).

   Thanks Martin. That's basically what we want, but I'd sure like a couple more choices. Taller building would be nice -- it would make the 'bubble-and-suck' more evident.

   I didn't think to search Flickr; I searched The Google for stack effect and didn't fine any images like this.

   I'll contact Chris, but we're still looking for a better photo. It seems to me I've seen examples of this in lot's of power points over the years...

   John,
   Yes, I've seen that slide before -- it must have been at one of David Keefe's presentations. Thanks, John -- you've got a good memory.

   Here's the slide -- maybe David Keefe has a high-res version of the photo.

   Thanks guys.
   That one is much more like what I had in mind.
   Anyone have David's email address?
