This photo, shot on the same day as the previous three photo, seemingly shows rays of light streaming from the clouds. I did this using a long exposure and zooming the lens at the end of the exposure without adjusting focus. I do not remember if I zoomed in or out. I also used this technique on a previous photo (http://potd.chrisempey.com/2008/06/20/20-zoom-zoom/).

Photos shot the same day:
A New Dawn
Sunday Morning on the Lake
Incoming Storm
