Cool veg, but also want some help

I have been checking out the files available from Sundance Media Group in order to improve my Vegas skills. After watching the ripple text and bubble text I decided to try one of my own. Using a noise filter, I gradually increase the noise so it looks like the text is slowly blowing away, like sand. I would like to improve the effect by possibly having the noise pulsate randomly green as it comes in because this will add some chaos to the sand as it goes of the screen since you can tie one of the color channels to a single displacement axis. Every pixel can't pulsate at the same phase, because then you would have all the sand moving around the same direction, and I want some chaos. I tried to use two noise generaters, and have the one I am currently using slowly become more transparent (instead of white) and show some undulating green noise below it that would add to the choas.

Enjoy the file and thanks for any advice you may have to add the choas.

Green sand?
You can control the hue easily by changing it over time by setting up key frames. If you want to go from white to green, just push the G color slider all the way to the right (last frame) and the R and B all the way to left. If you want the color of the sand to stay constant, don't add a last keyframe. I would think the text would slowly change as the sand covered it.

Chaos?
To add more interest try the PluginPack shatter 3D filter which will break the text up and rotate it too.

No, I don't want the sand green at all. Did you view the .veg file? Currently the text is tied to some generated media of noise as a displacement map. This noise slowly goes from all black, and pixel by pixel slowly turns white. As each pixel turns white, it causes a pixel of the original text to look like it flies off the screen, like sand.

The red channel of the noise causes a displacement along the X axis. The green channel causes a displacement along the Y axis. So as each pixel of the noise slowly turns from black to white, I would also like each pixel to pulsate with green (or red, doesn't matter) which would cause the text pixel to wiggle a little bit as it flew off the screen. If I adjust the sliders as you suggest then all the 'sand' wiggles exactly the same so there is no chaos.

I will try some more with the shatter 3D plugin, but I am not sure that it will still look like sand since you can only have 16 subdivisions.
