New York Shitty Day Starter: Househenge

The above arrangement (which is located at 146 1/2 Java Street) has long been a fascination (and personal favorite) of mine. For this reason I make it a point to walk by periodically so as to see how this ever-changing creation is progressing. Yesterday I noted a couple of new additions without further ado, here they are.

A wall.

And this rock garden.

Does anyone have the 411 on what this is about and/or who is responsible for this? Quite frankly I am fascinated and need to know! If you have anything to tender regarding this Garden Spot mystery please do so via comments or email at: missheather (at) thatgreenpointblog (dot) com. Thanks!
