One of the pleasures I had walking in Montreal was to admire the lovely games the Northern sun liked to play on brick buildings, and the mysterious manmade mechanisms for which I had to find a purpose. Like what I chose to see as a memory tube in the second picture here, a spatiotemporal channel projecting a Parisian window onto this Villeray inter-floor.
Note: this is another exercise of mixing my own photos (the Montreal background) with archival photos.
