Hi there,

Since the IRTC is back again, it seemed a good idea to jump in and make 
  an image. Staying on-topic of rebirth, plants and seeds are a suitable 
topic to make a not to complicated scene. So, there i go, making a 
dandelion seed (just flying away from the flower). The problem now is, 
how to make the seed head? At the moment it is a scaled sphere, but it 
should be more like this image (yes, i know, i am shamelessly 
reproducing the image :-)):

As you can see, there are dimples in the surface. My idea would be to 
make a surface with blobs. But how to place the blobs? The dimples 
should be evenly distributed over the surface (like a golfball). The 
only thing that comes to mind is to place the dimples randomly, and then 
iterativly let them "find" the place where they are the least close to 
their neighbours. Needles to say, this is complicated and a project on 
its own.

So, any pointers?

Thanks in advance,

JWV
