I've seen card stacking before, and as a child, loved to make my little houses. But even if I try my whole life, I could probably never come close to the kind of card stacking Bryan Berg does. Trained as an architect, Bryan has the nohow and patience to make incredible structures made of cards.
And here's the most incredible thing. He does it without tape, without glue and without trickery. He really builds, and builds so well that his method has been shown to support 660 lbs per square foot. His record design took 218,000 cards, and took him 44 days - a replica of the Venetian Macao.
