Twelve-year-old Leon McCarthy was born different. Due to a complication during gestation, Leon was born without any fingers on his left hand. Thanks to his persistent father Paul McCarthy, a special effects artist, and a state-of-the-art 3-D printer, Leon no longer sees himself as different. He’s special, he says.

CBS Evening News’ Michelle Miller caught up with Leon and his dad last month. Since the story has been picked up by additional news outlets, including FoxNews, msnNOW, and NPR.

What’s so appealing about Leon’s story that it warrants so much media attention? Prosthetics are nothing new. Archaeologists found an Ancient Egyptian prosthetic toe fashioned out of wood and leather when excavating a tomb in 2000, LiveScience reported. Prosthetic limbs have come a long way since then. Prosthetic legs have become a routine sight around Boston, where dozens of people injured by during the Boston Marathon bombings are learning to navigate on their new high-tech legs.
