Art of Blender
The Art of Blender is full of inspiring renderings from Blender artists around the world.
In this video tutorial for Blender 2.60 we introduce you to the basics of character rigging. This tutorial covers the initial armature creation, working with Inverse Kinematics (IK), various constraints, defining deform and control bones, and setting up basic drivers for extra control.
The character model used comes from BlendSwap by Blork: http://www.blendswap.com/3D-models/characters/low-poly-character/
