Powerpoint Slides for Everyone -2013 - Week 17

Each week I make a new background image for Powerpoint (or similar presentation program).  I make them for use at my little church, but you are free to download them and to use them in your own projects at home, work, school, or church.  Use them however you like. 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 such things, this pic began as a close up of an old radio tuning dial.
