There are 1686553615927922354187720 possible combinations of arranging the 24 cards in the animation. (To put it in perspective: if every person on earth (some 7 billion) would do one combination every second, it would still take around 8 million years to lay down all possible combinations. One could say the duration of the piece approaches eternity. Right now, it takes about 6 seconds for a new image to appear in the animation. That makes the "duration" of the piece about 1.01193217x1025 seconds or 1.686553616x1023minutes or 2.810922693x1021 hours. "The Road" is a work of immense proportions).
