Random vs. Noise

Hi all,

 

Although I've been an After Effects user for  many years, I am a beginner to expressions. They intimidate me, but I'm  noticing how powerful they can be to my workflow. At any rate, here's  what I'm trying to accomplish. I would like to be able to place 3D  layers at random coordinates in 3D space by simply duplicating the  layer. I was able to accomplish this, but it doesn't have all the  functionality I would like. Here's what I've come up with:

 

posterizeTime(0.00001);
value + [random(-1000,1000), random(-1000,1000), random(-1000,1000)];

 

The problem with this expression is that I cannot add  wiggle to the position because the posterizeTime inhibits it from  working. Is there any way I can accomplish the functionality I desire  with noise, or another method for that matter? I'm just not sure how  noise works. Any ideas?

 

Thanks in advance.
