Sculptural Wall Install

I am on a major push to finish some things up around here.  Enough that I can just chill out at home.  I'm not going to make a real list like last time, because that's just depressing.  Possibly more because of how much I change my mind as opposed to how much I didn't get done.  (But that, too.)  I'll just continue to share some progress thoughts here, if you don't mind.

Like this new idea for the upstairs hallway: molding that acts as sculpture.

(via Adore Home Magazine)

It seems easy enough to accomplish, though the simple way (installing full sheets of progressively smaller plywood squares) seems a bit heavy for the wall to sustain.  I would also leave space between each large rectangle.  But I love that the interest comes from the dimensionality rather than a color, pattern, or texture.

Still mulling it over.  What do you think of this?
