Futuristic Finger with Working Joints

I created an finger that was inspired by popular video games and my future career choice. To make it more like the fingers in videogames I play I created shielding over the joints, rather than just the basic shape. Their unique shape not only provides visual appeal but also ensure that the finger will only bend in the proper direction, interlocking to form a relatively smooth surface. The finger has working joints and is to scale.
