Thanks!

The soil is a pain.  If the colors get too grainy then the ant disappears
(can't see it very well.)  I'm still trying different methods and sizes
though.

The smoke isn't what I want but so far I haven't found any good examples
that look like what I need.

Yes, you are right the lenses are nothing more than squeezed spheres.  I'll
test with your version next.
