11 Spring Street, Nolita, Manhattan.
For some time now (years?) this mystery building has exhibited few signs of life apart from the electric candles and carefully placed white drapes in each window. Lockhart Steele reported back in May that it was for sale.

A Gawker correspondent noted that the building is a favorite and famous canvas for street artists.

I took these photos last month. The building is apparently still for sale.

More info from Gawker readers here and here.

Yet another Gawker reader reported that this similarly spooky old bank building at Spring and the Bowery is the home and studio of the photographer Jay Maisel. Interior photos of basketball court etc. here and here.

It's not just an Apple fan site. It's a site "devoted to those who camp in front of (ifo) Apple's stores" in order to be the first people inside on opening day. Now that's specialization.
