I wrote about this last September, but other people have been talking about Zeus which is actually in the field and while very cool doesn't have near the coolness that Close Quarters Shock Rifle has.  I did some more research on it and found another article.  I can't talk about the briefing and pictures I saw last summer, but think Startrek Phasor and/or a Starwars light saber:

While I was talking with Pete Bitar, yesterday, I told him that basically, with the XADS Stunstrike CQSR "you're shooting lightning at people", to which Pete said something to the effect of "yeah, that's pretty much it". What's interesting about the StunStrike is that the lightning bolt that comes out is visible (just like natural lightning), and has an ending point, like a light saber. Pete told me that the electrical "beam" is both visually and audibly intimidating, and should prove to have a profound psychological effect on people. Basically, it looks and sounds scary, which is usually what you want with a less-lethal device.

Imagine a mob of Allah worshiping thugs trying to storm a US embassy calling us heathens and blasphemers.  A couple of Marines on the roof then educating them on the name of the one true god, Uncle Sam, and strike them down with lightening bolts from above.  I get all warm and fuzzy just thinking about it.
