Power Noise + Houdini FX Tools

Based off the Houdini FX Tools: Heavy Smoke digital asset's shader. I re-wrote the entire thing in VEX, and implemented the so called "power noise" that my fx lead uncovered.

Here's a XSI implementation by my CG Supervisor @ rsp: http://blog.ioxu.com/?p=19
And my fx lead, well he's got fractal stuff cooking @ http://www.incubism.com/dan/

It's amazing how easy it is to do stuff like that in houdini. (And XSI of course!)
