Spider Spinning its Web at Night

I've been through about 450 photos today, and this is one of the few I feel like posting because it is interesting. I got the shot by experimenting. After taking dozens and dozens of pictures of a beautiful full moon over Lake Allatoona (and not being extremely happy with any of them), I saw a big spider on its web just to my left. The web was large and spanned a space between a pine and the dock on which I was standing. I took off my headlamp and hung it on the end of a stair rail to illuminate the center of the spider web and waited for the spider to crawl to the center. I put the SB800 speedlight on, and fired away. This was taken over an 8 second exposure. The flash froze the image of the spider when it fired, and over the rest of the time, it crawled up in a J-shaped route toward the center of the web. 8 second exposure @ f/2.8.
