SaberMania!

This is a game a found in FlashPlayer (home of the coolest flash movies ever....). It's where you use your mouse and two letters in your keyboards and lightsaber Duel.

I advice you take all the tutorial you can, because trust me, you are really something if you can master this (or at least play good in it). The technique is really confusing. I got my A$$ kicked in every single duel.
