Painting with Light

I know I already did an out-of-focus Christmas tree light photo, but when it's 9:00 and I haven't taken any pictures all day, it's kind of an easy fix. This time I added a slow shutter speed and some motion. I took 90 pictures like this, adjusting the focus (which changes the size of the "brush"), trying to get just the right motion to make an interesting picture. I think I like how this turned out.

I'll try not to resort to this too often...but it's just so easy and kind of fun when I haven't taken any other pictures all day.
