Ever since the Episode VII teaser trailer was released, brickfilmers all over the world have tried their hand at recreating it in LEGO. There are some impressive recreations out there, but one of the best and most accurate would have to be the one created by FinalFeature. It features some very good visual effects on top of the animation and matches the framing and colors from the original trailer very closely. He claims to have made it in 22 hours of non-stop work, which makes it even more impressive. You can discuss the video here and see more pictures of his MOC of the speeder from the trailer here.
