I decided to try to take a picture, expecting a big blur, but I had to try anyway. What I got was pretty cool. I used Dustin as a tripod. He's 21. He's 5'9" tall. If he could have held still, he would have been perfect, but he couldn't and this is what I captured.
These are the exact images. I have them at higher res on my card so I can see how squiggly the lines are, but those are the entire images. Not cropped or otherwise changed. The shutter was open for a good twenty seconds at least. I think this is really neat.
