FreeBody, Block(1,1,1) : (mass=1.0, color="red");
The first four lines set the simulation up, defining the camera, gravity, and the default surface. The last line of the code is what sets the simulation in action. A single block, of size 1 meter on all sides, is suspended in the air and set free. The Block has a mass, and a color is set for its surface.
