Tenement Voyeurism

I was passing by my local art gallery today when this particular work of art caught my eye. I adore it. The detail, although not clearly evident in this shot, is incredible, in showing many of all the residents of this Glasgow (?) tenement engaged in some aspect of their daily lives. One feels quite voyeuristic, as though gazing in from a similar block across the road.

Unfortunately I can't tell you at this point who the artist is (the shop was still closed for the holidays and there was no name on the piece), but if it's still there when I'm passing again I'll let you all know (unless of course anyone does already know).
