I've recently put up pictures of my Dooku custom fx lightsaber and the chain, but I figured I should share the whole costume:
That second photo really needs some work. You can see my hands. The cape should be everted (which mine does do). The sun is drowning out the color of the blades. And you can't tell that Anakin's holding a Dooku saber. I guess we'll have to correct those at AdventureCon.
