A heroic set of prosthetic hand designs will soon allow young amputees to transform into their favorite Disney characters. Whether they prefer a red Iron Man gauntlet, one of Queen Elsa's sparkling blue gloves or a hand inspired by Star Wars' iconic lightsabers, they'll be able to take on the world with a prosthetic that finally marries form and function. The three models have been created by Open Bionics, a startup working on cheap, 3D-printed hands for amputees. Joel Gibbard, the company's founder, says they'll cost around $500 and be available in 2016. Another, non-Disneyfied design should be roughly £2,000 ($3,071) -- considerably more, but still a fraction of what many existing prosthetics cost.
