Well there are many examples to look at when it comes to Cyber hands, take movies like->
I Robot
RoboCop 1 2 3
Class of 1999
Star Trek: First Contact ( ..wait..just a suggestion !)
Nemesis 1 2 3 4 ( has a female body builder as a hero robot in the 3 last movies :p )
Cyborg 1 2 3 ( Angelina Jolie stars in nr.2 )
Terminator 1 2 3 4
American Cyborg: Steel warrior
Steel frontier
Steel dawn has Patrick Swayze in it.
Cyborg Cop ..no wait, they suck and use a robotic glove...
Some..well a lot of these movies suck hard but they can give some indication or hint towards different hands...if anyone has these they can pull some stills here and there, just to give a illustration to other hands.
