Then try placing the blob components in a similar way.  You don't 
necessarily need a spiral pattern, other regular patterns or random but 
uniform distributions like used for radiosity might be useful as well. 
Try for example the halton sequence Mael used for radiosity some time ago.

It is part of MegaPOV 0.x.
