Its been done before, Berthier is just a copy cat. I've seen dozens done by Hugo in Charleston 1989.
My favorite was at a floating dock marina on Lake Norman. It was not named by the artist but soon was called the stack pack w/sprinkles on top. Each time a blown away 22-27 footer hit the gas dock Hugo would remove the deck at the joint. Within a short period of time four were stacked up within each other very uniformly. The sprinkles were the icing on the cake. Those floating docks were fitted w/ 12' long styrafoam blocks. Hugo used all of the blocks in the marina. I started seeing the sprinkles about four miles before I got to the marina. But I couldn't even give it away...no London bankers in SC.
