tree house shapes

I dream that someone in space says to me: So let us rush, then, to see the world. It is shaped like an egg, covered with seas and continents, warmed and lighted by the sun. It has churches of indescribable beauty, raised to gods that have never been seen; cities whose distant roofs and smokestacks will make your heart leap; ballparks and comfortable auditoriums in which people listen to music of the most serious import; to celebrate life is recorded. Here the joy of women’s breasts and backsides, the colors of water, the shapes of trees, athletes, dreams, houses, the shapes of ecstasy and dismay, the shape even of an old shoe, are celebrated. Let us rush to see the world. They serve steak there on jet planes, and dance at sea. They have invented musical instruments to express love, peaceableness; to stir the finest memories and aspirations. They have invented games to catch the hearts of young men. They have ceremonies to exalt the love of men and women. They make their vows to music and the sound of bells. They have invented ways to heat their houses in the winter and cool them in the summer. They have even invented engines to cut their grass. They have free schools for the pursuit of knowledge, pools to swim in, zoos, vast manufactories of all kinds. They explore space and the trenches of the sea. Oh, let us rush to see this world.
