This cool work, known as Digitigrade leg extensions, is done by Seattle-based sculptor Kim Graham.
They are made of steel and add 14 inches of height to the wearer. But these are not ordinary stilts; they give a person the uncanny and graceful appearance of an animal. It is really cool! The movement of the legs is genuinely graceful and naturalistic. It is a great deal of fun being so much taller.
In this video, Kim Graham shows how they work. You can buy yourself one also. The core leg extensions are between $750 - $780 plus tax. The spring loaded hooves are $200 extra. Here for more infomation.
