The Building Centre: Birdhouse?
More self-explanatory in large?
Well, I think it's crystal clear what's going on here...
Met a friend at Gentleman Baristas in The Building Centre on Store Street, and killed a few minutes in the "meta / physical" exhibition; I found myself drawn to this exhibit, but didn't read the label, so have no idea what it represents. *shrug*
Other street, exhibition, and travel shots are on this page (or right from Cycles and Shadows)
