BTW Eric, here's a quick little time-lapse I did at IISAC09.

I was only mucking around, so it's nothing special, while I smoked my cigar and went around to annoy the others, LOL.
I plonked the camera down (20Da) on my tripod, set it to 1600 ISO, Daylight WB, 25 sec exposure and ICNR (50 sec total plus 10 sec delay between shots) at 16mm, f/2.8 and let her rip.
So I ended up with 1 shot per minute.
The activity you see is the guys mucking around with the sparklers and red light torches.
Unfortunately we got clouded out soon after.
I used the jpgs, resized them all in VirtualDub down to 800 pixels and assembled them all in Startrails.
This gives you an idea of what to expect.
