There was a fashion, around the time of my childhood, for "crazy paving". This seemed to involve taking perfectly serviceable rectangular concrete or stone paving slabs, breaking them into large pieces and laying them with narrow cement lines between the pieces. This had the advantage of, among other things, disguising the poor workmanship of an amateur because there were no unforgiving straight lines like those produced with unbroken slabs to reveal the novice's work. We recently went to a wildlife park with young children, and in observing giraffes more closely than I'd ever done before I was struck by the way their colouration resembled crazy paving.
