The title for this post is mostly wrong. It's no longer 2015. I made these background images - one a week - to use and to share. But had forgotten (until reminded by my friend, AJ) to share the completed collection in one easy .zip file as I have done in previous years. (2012, 2013, 2014)
And this collection isn't quite complete. There are images for 46 'regular' weeks and 4 for the season of Advent. Apparently I missed the last two weeks of the year. Not sure what happened, but ... 50 of 52 isn't so bad, right?
Anyway, the collection is yours if you'd like it. Use the images at home, work, school, church, on the moon, in the sewer, on your cell phone... wherever. I only ask that you share them freely and that you tell others you found them here.
