Powerpoint Slides for Everyone - 2014 - Week 48

Once a week, every week I post these free background pictures for you to have and use as your very own.  Use them in powerpoint slides (or in another presentation program) or use however you like.  If they're useful to you, they're yours.  If they're not useful, but you like them, they're yours.

I only ask that you share them freely and that you tell others that you found them here.

This particular picture was taken at the Smart Museum of Art in Chicago; it is a close up of a piece of sculpted stainless steel.
