Does anyone know of a good way to add some random jitter to a poly object. I'm not talking about the whole object, but rather the vertices. I tried making it a softbody, and adding some turbulence, but that only seems to make the verts move (albeit randomly) consitantly in a direction. I just want each vert to move a little bit each frame, never diverting too far from it's original position so that the basic shape is always still visible.

Anyone know what I'm talking about here or am I making no sense whatsoever?

Thanks.
