My KaleidaCam theme month continues. I have been rather lax in posting them. This is what looks like a drain grate, but it is vertical -- one of two on one side of a concrete display board that's maybe 6 inches thick. The structure is solid on top so it's probably not for draining anything -- maybe they pipe music or other sound through it sometimes? I've never noticed. A non-kaleidascopic picture of it is posted here in my Alternates album: http://365project.org/mcsiegle/alternates/2017-08-18
