Time-Lapse Motion Lego Rig

I spent some time this weekend playing with my Legos.  To be specific it's my Lego Mindstorm Robotics Kit!  As proof of concept I created this time-lapse motion rig.  I was taking a shot every five seconds and I found the best way to sync my camera to the rig was to use the mic and sense when the shutter released.  I've got some ideas on how to make the whole thing a lot better and it's a hell of a lot cheaper then some professional rig.

Here's the video.
