This is the result when you drive in a tunnel at 80km/h(50mph) while taking a picture with your camera you had set on the dashboard.
I drove through Göta tunnel in Gothenburg(Sweden), which has these cool blue lights in the midsection, 4 times to get this shot. Each run with different aperture. This one was at f8 and 6 secs exposure and captured during the 3rd run.
I thought I'd make a wallpaper out of it while I was at it...
