A neanderthal walks into a room. Inside are a man and a woman with large sticks, surrounded by dozens of unintelligible glass discs and squares. The man (with the stick) comments he can see the ocean under the clouds. Why?
The Neanderthal walked into a plane cockpit. The people with sticks are the pilot and co-pilot, who are holding onto the control sticks, are discussing the scenery (through the clouds below, they can see the ocean). The glass shapes are the windows and the various buttons for controlling the plane.
The man and woman are playing pool at a bar on a cruise ship. They are holding pool cues and are surrounded by the bar's cylindrical glass tables. There are a number of rectangular LCD TVs suspended in the room. As the sunlight slowly whisks away the heavy morning fog, the man remarks that he can finally see the ocean under the clouds. Clouds of fog, that is.
