This is a heartwarming video of Iron Man Robert Downey Jr. presenting 7-year old Alex, who was born with only a partially formed right arm, with a new Iron Man robotic arm. The arm was 3D printed by the Limbitless project, and presented at zero cost to Alex's family. That's a pretty sweet looking arm. Me? I just gave myself HULK arms. "You spraypainted them green." You're very observant. Now hop on my back, Alex, and let's go do whatever it is superheroes do. "Fight bad guys?" Okay how about we play video games instead?
Keep going for the video.
