“You step through a rectangle to leave the bedroom, step through another to wash (perhaps using a cuboid of soap), dry your skin and hair with a rectangle, and check out your reflection in the rectangle. Make your way to the kitchen and open up the rectangle that shields the cold things; perhaps open another rectangle to warm something up. Take it from the counter rectangle and eat it on the table rectangle, sitting on a rectangular platform. Wipe your face with a rectangle. Leave the house through the rectangular portal, making sure you carry your necessary rectangles for identification, payment, work, and entertainment. Then you really enter the land of rectangles: the walls, the steps, the parking spaces, the sidewalk blocks, the signs, the crosswalks, the vents and gratings, all the windows, and every discarded wrapper of a rectangular eyeglass wipe.”
Whole article is worth a read as it follows up this mind-blowing revelation of the humble rectangle’s omnipresence by tracking down the world’s first known use of a rectangle, the appearance of shapes in nature, and a theory about 2001: A Space Odyssey.
