Volumetrics are in Cycles!

So Cycles has volumetrics now so I thought I'd do a quick test.  This scene has no lights except those coming from the volume.  I'm sure they're working on point densities which I think will greatly help scenes like this.   As for the movie, I've been stalled for a long time because of work and moving households.  Now that things have settled down a bit I think I'll start in again.... sorry for the long time between posts:)
