The design principle, in either case, is rows of square-headed stones on a 45 degree bias from the edge, 5-20 mm between any two stones. Time does the rest, creating contours and settlings--let's call them textures, rhythms--depending on degree of foot, car, tram, bus traffic.
The diagonal orientation is design genius, I'd say. Let's try it in Regina. Climate heaves? With the stones kept small enough, we could avoid the seasonal wreckage we see in our pavement and concrete. Hard on cars? Too bad!
