In the basement of a house in Burien, 20-year old Peregrine Hawthorn shows me his three hands dangling from a chord. He loves them. He assembled them himself. They look like robot hands.

The components of each hand were made by a 3-D printer for about $50 dollars with the help of an organization called E-NABLE. This is much cheaper than a high tech prosthetic hand which can cost more than $100,000.

He calls one of the hands that dangles from the line the "Cyborg Beast."

A research idea that was supposed to give people super-powered legs is instead helping stroke patients and other people who can’t walk. 

It’s a new medical device, using a combination of springs, cables, and Velcro. The inventors in Seattle are hoping to transform the possibility of recovery for thousands of people.

The idea started with a horse.
