Indeed you did. Sorry for the duplicate question -- I figured a forum like this was more appropriate than MD's discussion board for an expired drop. ;-)
Your work inspires me, and I'm going to keep at this "problem" for my own purposes.
I'm wondering if there's a way to design a kind of "light spreader" that can solve the uneven illumination problem. I know the stem will always be in the way, but I'm thinking there's got to be some simple way (a clear O-ring / silicon mold / fiber optic bundle / or other device) to get the light to bounce around and fill the cap more evenly.
I'll put some brainpower into and see if something dawns on me. In the meanwhile, I'm open to suggestions. =)
