No no no, guys, this gif set leaves out the literal best stuff from the video.
So a few years back, this guy who accidentally cut off his fingers, teamed up with a special effects artist/puppeteer and created a 3D printable prosthetic hand, that used the movement of the wearer to be able to grab things. The guys who did this said they were just going to post the schematics online, which in turn lead to creating a network of people with 3D printers, who were willing to print prosthetics for people. The network of volunteers, turned into an organization that gives prosthetic arms/hands to kids who need them. They have science types improving the designs and creating new ones, they got a grant from Google, classrooms and scout troops are getting involved and making prosthetic hands for people.
