In the Distillery district of Toronto, yet another Strand/Weston/etc careful placement of shape and shadows, but I thought I'd give it a funny and obscure title.

I find that it surprisingly well describes the thought process going on when you're doing abstracts: empathizing with a purely geometrical subject.
