(The answer to this one might be Google-able, but my fu is weak today.)
I can see look out my apartment window and see the top of Philadelphia’s City Hall.
Here’s my view.
I will be done with school in this city in May 2010. Will my view of William Penn be unobstructed by then?
Follow-up question: What on Earth are they doing at City Hall that requires the entire building to be covered in scaffolding?
Christo is in town. He wanted to use red, white, and blue bunting but John Street said no dice. So scaffolding it is. Think of it as the Mariano-proof fence. 
As far as the scaffolding in your pic, they are cleaning the statue and applying a protective coat of wax. This was done first in 1983 and is now done about every ten years and takes a few months to complete.

As far as all the other huge scaffolding that is used for cleaning the exterior, I have no idea. Maybe Milton’s restoration and cleaning crew bills the city by the “lap” and they just start over when they get back to the starting point!
i do hope they don’t have another 'free wm penn" drive. the last one was rather pitiful.
