I do tend to agree with them when they say;
     "Gravity -0.5? Why so many issues with gravity and geometry sizes?"

But then I use much higher values for gravity in my simulations, 
contrary to Nguyen's advice ;) without any problems at all.

"Newton is a worse case O(n*n) solver"
Not sure that's something to boast about is it?

Anyway, the movies are quite cool!

Cheers,
