As i said objector's bump looks better.
I will need some time to investigate if better bumps are a side effect of post-processing or superior math in Objector's fragment shader. I will report back on this issue in a couple of days.
See the attached video(s), using animation.
Wow!!!

What about the "human" brain you teased me with earlier?
-- Can this ball-shaped artificial brain be made larger to fill in the empty space in the skull? Can a few multi-colored light-emitting diodes (LEDs) be added to the golden "lock" plates and rotate together with the whole thing?
-- Why isn't the lower jaw yellow any more?
Press Ctrl F5 and look at the second animation video 
No, I like the ball brain better than the diamond one, just please make it somewhat bigger and add the LED's if you can...
