Looks like a crude form of radiosity, or an odd cross between radiosity 
and the proximity pattern. Unlike radiosity, it will have to do the 
samples for every evaluation of the pattern, so it will be inefficient 
and slow. The results won't be as good quality as actual radiosity, 
either, you will have to use a lot of samples to reduce graininess. The 
benefit is that you can use it on individual objects, but a better 
solution would be to modify radiosity to allow the user to specify which 
objects affect it and which objects are illuminated by it.
