For "fun money" I make and sell a Tutorial DVD that instruct on Lightsaber spins (aka flourishes) that you see in the Star Wars Prequels as well as other sword combat films.
It was a project that I started back in 2005 by having tutorials on YouTube and got so many request for better video and new "spins" that I decided to film a full tutorial video. I've sold DVD's to all around the globe to people so it's kinda cool.
Since then, some of my friends have taken it farther and have DVDs showing how to do full on choreographed stage combat with lightsabers.
This is the site:

If you wanna see the original YouTube vids you can search: saber spin tutorials
That's all tho...nothing serious.
