"In 1838 Charles Wheatstone published a paper describing a curious illusion he’d discovered. If you drew two pictures of something – say, a cube, or a tree – from two slightly different perspectives, and then viewed each one through a different eye, your brain would assemble them into a three-dimensional view. Wheatstone created a table-size device to demonstrate the effect: the world’s first stereoscope."
