I saw the metaballs mentioned at Phil's forum, it will be great if these Titans of Python can get together and make it work.

Oh, and I hardly like to mention it, but if a collaboration is on the cards, I'd like to request a way of making cuts in a mesh according to where a 3D surface intersects it - a bit like the Scissors module in Phil's Clothing Designer Suite, but not limited to working in one plane. I can wish, can't I?
