The scene is only lit with a sky_sphere; that's why it rendered so quickly.

This might just work, because the points /are/ created in vertical 
succession.

Even better yet would be Voronoi evaluation for all points, then I'd 
know the nearest neighbors. Unfortunately, Voronoi calculations for 
point sets are still beyond my capabilities :(

The biggest problem I'm having now is choosing when to subtract a 
bubble, and when not to. If a bubble resides inside another one, it 
currently subtracts that bubble. I need to maybe *add* that inside 
bubble, not subtract it.
