A stunningly beautiful steel-and-brass artificial hand from the 19th century. And it really really works! “The elbow joint can be moved by releasing a spring,” explains the website Science Museum, “whereas the top joint of the wrist allows a degree of rotation and an up-and-down motion. The fingers can also curl up and straighten out… The rather sinister appearance of the hand suggests the wearer may have disguised it with a glove.” Sinister? Maybe back then, but now it would be classified as steam punk. (via Neatorama)
