Buying your son a car goes a long way towards proving your success as a father, but this carpenter from Vietnam actually carved a life-sized car for his son out of wood. That was a while ago, though; more recently, he presented his son with a replica of his favorite World of Tanks machine.
The talented master has plenty of richly detailed vehicles in his portfolio, including a tank conversion of the Mitsubishi Delica, but the latest project is a real tank that uses dual electric motors to drive its tracks. It is actually drivable and performs maneuvers like any real tank would.
According to the master, he spent three months perfecting the build. This seems like no time at all compared to the sheer volume of work involved. Make sure you watch the video, which details every stage of this fascinating project.
