Gold - Howling Pixel

Gold is the most malleable of all metals. It can be drawn into a monoatomic wire, and then stretched about twice before it breaks. Such nanowires distort via formation, reorientation and migration of disloions and crystal twins without noticeable hardening. A single gram of gold can be beaten into a sheet of 1 square meter, and an avoirdupois ounce into 300 square feet.
