"Braveheart" meets "Star Wars"

So in DMA499 we are covering compositing and special effects for motion graphics. One of our tutorials was to give a soldier in the movie "Braveheart" a light saber. Using the Pen Tool, Layers, Masks, Gaussian Blur  and tracking in After Effects, you are able to create a light saber. In the original clip, the guy is just holding a sword, after using After Effects, he now holds a light saber.
