Hmmm... ok. So a random placement of centers (within the unit box) is 
not possible; think for instance of rain drops on water. For the time 
being I probably can get away with un-even scaling for my project, 
although that shall deform the pattern I guess. Maybe an average of 
different randomly translated patterns would do the trick? I shall try.
