On Wednesday I was in Helsinki on my day off. There was a big construction site just next to Stockmann's Christmas window, and I had to take some photos of the wonderful pavement they were laying there. It is a pedestrian zone, and the tiling will cover a 250 m long area. This first part is 50 m long.
Isn't this a perfect (and difficult) quilt pattern?
One more view. The yellow shade is only a reflection on the water, the slabs are in grey and red granite.
