Have you tried using a good macro lens?
I guess I need to take back what I said, but getting this shot required using a direct light source, switching to macro mode, locking the focus/ exposure, and a few tries. With my Rezound it was as simple as tapping the screen to focus and it took care of the rest.

That looks pretty good. I can't ever get mine to focus.
