Funtastic Hand is the first playful prosthesis in the world that it´s a toy at the same time. Every kid loves to play and build things using LEGO. That´s why this prosthesis was created, to let the kids build it by themselves. It´s a mix between technology and LEGO that a kid with disability could build. It´s easy to use, easy to put and gives autonomy to the kid to develop his imagination. Besides it´s a tool for kids with disability to reintegrate to society and so that they could interact with other kids through playing.
