In order to tackle the scope and breadth of the project ahead, Winston designated a group of teams that included both artists and engineers. To give you an idea of each team's complex responsibilities, meet "Team rex," which consisted of 12 operators performing widely varying functions. Constructed from a frame of fiberglass and 3000 pounds of clay, the 20 foot tall T-rex was covered with a durable yet delicate latex skin and then painted by a team of artists who blended a rich palette of colors to bring his body to life. The T-rex was then mounted on a "dino-simulator," an imaginative mechanism inspired by hydraulic technology and based on a traditional six-axis flight simulator used by the military. On this motion-based foundation, both the platform and the T-rex could be actuated through a computer control board.
