For chess fanatics, what can be better than your own giant chessboard? It may not be quite Harry Potter size, but it's still big enough that it's easy to watch the action even if you're not standing next to it.
Whoa!! Fun way to add just a bit of green and a whole lot of whimsy to an outdoor space. Although this looks like a VERY pricey installation (outdoor wall-mounted TV, full bar, penthouse/rooftop location) the chessboard idea could be used even in a smaller patio area.
