This is IKO, a prosthetic arm for kids developed by Carlos Arturo Torres. While most prostheses are designed for utilitarian needs that work well for adults, it can be hard for kids who want to play with toys. This is a design that allows kids to have a hand but gives them attachments that work with Lego parts. I think this is compassionate design that addresses the desire of children to simply play that is overlooked in conventional design, and as a product it lessens the stigma of disability for children with prosthetics.
