Background Images for Everyone - 2015 - Week 24

Here and now (as we do each week around here) is your free, weekly, background image.  It's yours. It's free.  Download it to use in powerpoint (or similar presentation programs).  Use it as wallpaper on your laptop or smartphone.  Print it out and use it as wallpaper in your bedroom, if you like.  I only ask 1) that you share it freely and 2) that you tell others that you found it here.
