Oh my goodness gracious, what you can buy off the Internet in terms of overhead photography. A trained ape can know an awful lot of what is going on in this world, just by punching on his mouse, for a relatively modest cost.
You can drop a mouse down a thousand-yard mineshaft; and, on arriving at the bottom, it gets a slight shock and walks away. A rat is killed, a man is broken, a horse splashes.
