Prosthetics can't replicate the look and feel of lost limbs but they can carry a lot of personality. At TEDxCambridge, Scott Summit shows 3D-printed, individually designed prosthetic legs that are unabashedly artificial and completely personal -- from macho to fabulous. Scott Summit uses his 20 years of experience as an industrial designer to make artificial limbs that help people take personal control of these intimate objects.
