John Vallon is a freelance artist and inventor. Ferb is a large mass of aluminum filled with motors and encoders. When Ferb is filled with electricity, his lifeless body starts to move. When John Vallon is filled with coffee, the same thing happens. When the two work together, they can move a camera with tremendous percision and repeatablility to achieve camera movements not possible with a fleshy human operator. John Vallon is a dad. He has a great workshop and his kids spend a lot of time out there with him. He has all his fingers and both eyes, which means he knows how to be safe around dangerous machines. Hes also happy to answer any weird questions about robots and motion control and art. Give him a shout below.
