Here are some Rigged Hands. Awesome for VR projects because I updated this product over time by having an open ear and mind for my customers :) And my updates for this hand will continue, just give me some input!!! http://wp.me/P3dmoi-1yg Each finger can be controlled with only one control-bone per finger and there is a separate bone to clench a fist. Without subsurf modifier one hand has 512 faces, ideal for modern first person shooter, I think.

Here are some projects where this hand has found a use: 3d hand/arm manipulation and implementation of a data glove in Blender Game Engine. https://www.youtube.com/watch?v=ARkPq8giZ5s
