1.    An animation in wire frames.   

2.    Hand image sequencies from different cameras for a same hand animation  (the larger one is from the movable camera, others from fixed cameras).

3.   Natural gestures (hand constraint applications):

• bending the index finger at the DIP (the tip) joint: rotations at the PIP (the middle joint) occurs.

• bending the middle finger at the MCP (the third/base) joint: other fingers will move.

• bending the ring finger at the MCP (the third/base) joint: other fingers will move.
