I was thinking just this last night as I was driving across town to an
appointment, thanks to you (cue the "You Know You've Been Raytracing Too 
Long" thread...)

Keep in mind that blobs don't actually texture the individual elements.
I think they texture each intersection based on a weighted average of 
the textures on the components that contributed to that intersection,
though I'll admit that that's one area of the code that I don't have
memorized yet.
