German company that studies animate motion patterns and several aspects of visual perception and cognition created this neat Flash tool that demonstrates that biologically and socially relevant information about a person is conveyed in biological motion patterns. It allows you to manipulate a number of parameters controlling the characteristics of human walking. You can interactively change biological properties, personality traits and emotional expression of a point-light walker.
