I'm hoping to have something set up to make the move back n forth the way they're meant to - I was even toying with the idea of making some kind of PIR sensor set them off for a period of time, so when the dog detect movement, it's ears move, and possibly his eyes brighten up - one of a hundred ideas and now there's no timeframe involved (I was toying with trying to get this done for the coolermaster case modding competition) there's no reason not to try to make them all come to fruition...
