But perhaps you do not have an open-air shower. In such a case, you could do a lot worse than install a glass brick window in your indoor bathroom:
Come closer. Take a look:
Can you see how the view from outside is transformed: the slender betel palm stalk, the jumbled greenery, the wooden side-wall of the house -- twisted and jumbled in the bricks' kaleidoscopic eye; and shifting -- now this way, now that -- as you yourself shift on your feet, now a little to the left, now a little to the right? Can you see the little yellow veins in the cocoa wood? And the flashes of green lightning in the bush -- like the green flash in the peacock's tail or in the setting sun over the ocean?
And can you believe the impossible twistiness of the palm-tree stem? It seems to want to tie itself in knots.
