The problem with the way I shot the blobs at the surface is that they 
are just randomly shot at the surface. Photon-mapping has a more 
efficient way of doing this. The photons are shot at the target object 
in a spiral pattern, and therefore cover the surface more completely 
with fewer samples.

Chris Huff's blob pattern would be a great benefit. Is that part of 
MegaPovPlus? If so, I could get started on something right away :).
