He spends his days in a workshop building things like remote-controlled camera cars, underwater housing, even life-size rhinoceros vehicles. Head on over to Proof, National Geographic's wonderful blog devoted to photography to learn more about Boggs, and watch this great video below where he talks about working on such unique projects, and his creative drive to build things completely from scratch.
