Wallingford Traffic Circle

I am perfectly fine in having something "art-y" and fun be a centerpiece of a nearby traffic circle, but I'm honestly not sure what to make of this.

An old-school desk and chair left in the dirt? Why?

Is the whole point for it to sit in place, letting ivy and morning glory cover the furniture, eventually rotting to become a physical representation of the loss of public schools in Seattle?

Or did somebody get lazy and just dump some old furniture and skip town?
