Well mostly anyways. All I have left is to finish up the coffin lid to make it look likes he's busting out. I'll post up a video with a little walk through but basically its a simple windshield wiper motor on a motion sensor. The motion sensor also activates an 800 watt or should I say "800" watt marine boat amplifier which powers two outdoor speakers that are mounted under the coffin. The marine boat amp was an awesome find because it had an MP3 player input built in so all I had to do was add a sound effect track to my iPod, play it on a loop and when the motion sensor is tripped it blasts out the audio.
