I am deeply impressed indeed. Well done, Bill! I can imagine one of your 
iconic scenes using this set up.

One little point of attention, if you forgive me to "criticise"; the 
'cracks' appear to have about the same width everywhere and somehow that 
rattles a bit. Would it be possible to vary those a tiny little bit 
randomly through the object?
