A few little dots moving make a figure look male or female, heavy or light, relaxed or nervous, happy or sad. A fun tool to play with by Bio Motion Lab.
Another famous tool that I love, sodaconstructor, a Java applet that animates two dimensional models made out of masses and springs. In this one, emotion and anthropomorphism take place at the spring level.
A while back, Le ciel est bleu designed very successful moving creatures depending on gravity points.
In the robotic sphere, Guy Hoffman's lamp is designed as a collaborative desk assistant and this by following your intentions around your desk. Even if the lamp is non-anthropomorphic per se, its motion certainly gives it an anthropomorphic credibility that serves the function of a desk assistant. Video of its first steps!
