I'm new here. I was just browsing the forums and ran across this. I looked at that awhile back and noticed in the process that they use film and then scan the image. Did you look at the whole site to be sure?
ipix is working on a gigapixel camera. They have a reprint from GSN on their homepage that describes it.
Also, some nice fellow on the Yahoo stock board posted a like that I thought was really interesting. He was trying to get an idea of what gigapixel really means and found a link to a site that used 600 pictures taken over hours and took days to stitch together. The cool thing is you get some idea of what you can see because the image lets you zoom and look around.
I'm looking for the link on that board as I post this...it's actually 2.5GP.

So, that's something I wouldn't mind playing with!
I also think that Obzerv is pretty nice as well that someone mentioned earlier. I'm not in the biz though. I'm really into Stocks, but have taken a bit of interest in the subject since I became exposed to it.
Anyway, a gigapixel cam will be here before you know it. That's the good news.
