Did a test for adding lightsaber effects to live footage today. It's about 8 or 9 seconds long.

You can thank my friend JJ for helping me out as well. (was the fighter on the left, helped out with lightsaber effects in Maya, and did the audio work, and supplied the video camera)

Enjoy!

(and keep in mind that this is merely a test in preperation for a bigger project)
