The vidiot by Ib Melchior is a science fiction short story written in the mid-20th century. It centers on a television technician who accidentally discovers a way to see through walls, raising questions about surveillance, power, and moral responsibility. An ambitious TV “vidiot,” Don Hartley, is testing special-effects gear during a space-opera rehearsal when a shorted circuit turns a matte into a window that peers through the studio’s backdrop, walls, and out to the street. Mapping the effect, he realizes he can build a single camera—the “Hartleycam”—that could penetrate any barrier. Tempted by fame and fortune, he also envisions a nightmare world of total, inescapable observation and authoritarian control. After a troubled day, he chooses restraint: he visits his executive to confess only the equipment damage, accepts a second chance at work, and keeps his blueprints to himself, concluding that the world is not yet ready for his invention.
