Cenobite Wall

I went out the other day and had to take the metro to a section of the city I don't get to often, so I took the camera along for the ride. This building caught my eye from a block away. The entire wall was coated in yellow insulating foam with metal pinions sticking out. I am assuming from the spacing that the exterior will be redone in cinder block. I picked the right day to stroll by for an interesting photo.
