Hi!
Thanks for the quick responses and the most excellent ideas (common for the AM forum but not taken for granted)! I like the modeling approach which was the only way I could see. I had completely forgotten about Blobbies but it sounds like group opinion is that it would be easier to model and animate it (I've never done anything with Blobbies. I may be able to use these else where.
What I'm about is constructing a quantum environment and this effect, animated and a) perhaps rendered placed on sprites, or

used is for the virtual particle pairs (the spheres will be mostly transparent, they'll appear separate and come right back together). Besides just permeating 'empty' space (along with the Higg's ocean), they'll also represent the fields emanating from all (or most) particles (I might have to cut back to keep the clutter down).
The Higg's boson(s) and their fields (i.e. the Higgs ocean) will also be rough effect... I want it to look like a thick syrup and I have given no thought to this yet ** I will ask in a separate post with a better description of the effect so please post any ideas in that thread**.
Cheers,
Rusty
