Denver 2017 - Convention Center, Blue Trees

Such a curious thing, these blue trees around the Convention Center.  In post-capture study I learned that this was done by an activist artist named Konstantin Dimopoulos to increase awareness and decrease complacency about these vital living things that surround us.  In Denver they were painted beginning April 18th (we were there in the latter half of May) with a biologically safe, water-based and non-permanent paint.  Certainly got my attention.
