more fluid...

I played with Glen Murphy and Ben's "fluid" simulations (again and again!) and found them very interesting indeed!
however, alas, being a rather dull person, I'm having difficulties to comprehend the genius equations of Navier-Stokes, Lattice-Boltzmann, Rayleigh-Taylor, and the lot...
I wonder if anyone can help me understand a bit of the basic principles about simulating fluid in software, hopefully in the language of Britney-Spears, Bart-Simpson, or Oscar-Wilde 
Cheers!
(I heard the first person to solve Navier-Stokes equations will get $1000000 from clay institute!)

I'd tell you if I knew, but I didn't use any of those things in the fluid things I did (which is why they're not the most accurate things on earth). I tried to read up on them, but it ended up getting far too complex, so I did what .. 'felt' right.
(What 'felt' right was tempered by the reading I'd done on grids and stuff, but the core mathematics was all made up).

Thanks for your feedbacks, Glen. I guess you're right -- I'll try playing around with it a bit, especially about the "grid" concept...
Btw, I just re-discovered an area of "fluid" dynamics known as Heineken-Budweiser instability! ahh... it gives you a bad headache in the next morning
