Powerpoint Slides for Everyone - 2013 - Week 29

Once again we have come to this - a free background image for you to use in powerpoint (or similar presentation programs.)  I use them with my little church, but you are free to use them however you wish - at home, work, school, church, or wherever.  I only ask that you share them freely and that you tell others that you found them here.

For those who may be interested in knowing such things, this is a picture of some stadium lights taken through a cheap plastic prismatic filter.
