EN: The Biomotion Lab which is dealing with visual perception and cognition has a cool simulation of a walking human, the BMLwalker (flash needed). The human body is reduced to the most imporantant points of the motion. You can modify some parameters and see how this effects the walking style.
The lab seems to work in the analysis of motions which aims for an automatic evaluation the mood or intention of a person. So it could become a "Big-Brother-technology".
