I just built CVS and tested this file it works but you have to wait for  
the effect.

Now on a feedback note, why can the 3d view not show some sort of signs  
of the distance radius and other slider bar changes? The camera  
passepartout is a very good simple color feedback system for this kind  
of instant knowledge.

Other than that, it's cute. But a better work flow could be rendering  
out all channels of an image file like disfuse spec and alpha as a .psd  
and then postedit in photoshop or gimp.

Or work on Blenders seq editor as a basic post effects layer editor to  
go along with the multi layers image. Example: instead of setting the  
sliders and hitting render to see what happens the image could be  
rendered then the post effects options like gama zblur and other could  
happen in real time on the pre-rendered image, saving lots and lots of  
render and render and render again time
