Awesome work
I've done some stop motion stuff myself (though not for Newgrounds) and this is some quality stuff. The laser effects were impressive (probably not hard to put in using flash though I suppose). I loved the concept and ending. My only question is if you used any stop motion programs for this (example: istopmotion) because the animation is very smooth in some spots, then more jittery in others so its very hard to tell wether or not you just used a digital camera and moved everything a bit and hoped for the best.
Overall job very well done.
