We try.  :)
There's always so much to do, and it's so much easier to get things _done_ when
you can get past all the hurdles.  We all help out as best we can.

Find min_extent and max_extent of all the parts, calculate the centers,

With that many parts, I'd probably write a little macro that takes an object{}
as an argument.

Naturally.  Always a lot easier to get things moving with pre-built stuff.

Nice.   Chemist myself, but I dabble with things with my EE friend.
You should look up Rune's spider animation.  Very impressive.
