I'm not clever enough to name this guy so he is just MOAI.  Made of rigid casting foam, which has the desity of pinewood with 3D printed eye mechanism of our design.  He has 3 servos and our designed PCB and programming.  He wakes up when sound is heard and randomly looks around, after approximately 30 seconds he goes back to sleep for 5 minutes, if he hears sound after that he repeats looking around.  There is a knob underneath to adjust sensativity and also a "try me" button if you want to overide the 5 minute wait.
