rlm@513 3 In this thesis you have seen the =CORTEX= system, a complete
rlm@513 4 environment for creating simulated creatures. You have seen how to
rlm@513 5 - implement five senses including touch, proprioception, hearing,
rlm@513 6 - vision, and muscle tension. You have seen how to create new creatues
