Randomly moving objects on x/y or z-scale without keyframes

Hi Guys
Using ExtrudeNurbs i converted text into polygon objects. I would like to create an animation of the polygons randomly moving up and down on the y-scale position independantly of each other, without having to keyframe each polygon over a period of time. I also wanted to set maximum and minimum parameters for their movements. Can this be achieved. I have Mograph but not familiar with achieving it using its pluggins.

You can do this with the MoGraph Fracture Object. One caveat: the Fracture Object consumes a lot of RAM and cpu cycles, so you might not be able to use it if your text contains a very large number of polygons. Generally speaking, a few thousand is doable. Above that it depends on how much ram and horsepower you have at your disposal. Save first!
To make things easier, select all the text objects and connect them into one object. Delete the originals.
Then go into polygon mode, select all, and run Functions>Disconnect, with the "preserve groups" box UNchecked.
Now create a fracture object and make it the parent of the text object in the object manager. Go to the fracture object's "object" tab and set the mode to "explode segments".
With the fracture object still selected, create a MoGraph Random Effector. In the effector's "effector" tab, set the random mode to "noise" and check the "indexed" box.
Now it's just a matter of adjusting the noise properties and the position distance in the parameter tab ... assuming you haven't crashed your computer. ;)

Hi Adam
Thanks very much. Im sort of getting there. But how would I just limit the movement of the polygons to just one movement. e.g. I would like to just move the polygons up and down on the y-position? And also set the maximum and minimum height.
