I was in my car, bored and waiting for my granddaughter to come out of the movie theater. I had my new LX5 camera with me and decided to play around with it. I shot a few photos of the GPS unit on my car dash and this was the end result. I am not sure what created this weird, lighting-like effect, but it's very strange indeed. The "lightning" appears to follow the outline of the tree tops in the background. The car was facing toward the setting sun.
