Concrete 3D cladding

This is just the opposite of progressive vein-matching where there is no sequential pattern formation. Stick the slabs randomly and watch each piece of marble seek an individual character. You can choose between veins that are stark or subtle. If you want the character of each slab to be pronounced; go for marble types that have dark streaks. On the other hand, if you like something subtle, go for marble types with lighter veins.
