Here it is, once again, this thing I do every week - a free background image for Powerpoint (or similar presentation program). I make them to use at my little church, but you are free to use it in your own projects - at home, work, school, or church. Use them as you will. I only ask that you share them freely and that you tell others that you found them here.
-For those who are interested in that sort of thing - this is a picture of the flashing colored lights at a skating rink in Omaha, NE.
