     3    In this thesis you have seen the =CORTEX= system, a complete

     4    environment for creating simulated creatures. You have seen how to

     5 -  implement five senses including touch, proprioception, hearing,

     6 -  vision, and muscle tension. You have seen how to create new creatues
