Forward Kinematics Animation
This animation shows animation produced by forward kinematics.
It is a four link deep appendage with a branch after the second link
The first and third links have two degrees of freedom, the others have one.
The first frame is defined by rotation angles ((0,0),0,[(30,0),-15],[(-30,0),15]
The last frame is defined by rotation angles ((-30,60),-80,[(90,30),-135],[(-90,30),135]
