Dragging your shutter

Over the Holidays (which are still happening) I photographed a 50th wedding anniversary, and while I really like to do live events like that, there is inevitably some down time. During that down time where there are no pictures to take (I've photographed everyone in the room, the food, the decorations, even the building) my brain starts to think of different things I can do with my camera. This night I was thinking of Picasso's light paintings. So looking around I saw several Christmas trees that were just sitting there with tons of Christmas lights on them and I thought, What the heck. So I set my exposure to 5 seconds, focused, and then moved my camera in fluid motions, thus creating light paths from the Christmas lights. Here is the result.
