Two double-green-gelled flashes (580EX (thanks, Alan!) and 580EXII) @ 1/16 to left and right with baffles to keep the background dark, triggered via ST-E2.

The significant change compared to previous efforts was dumping the softbox and using the flash direct, which allows winding back the flash power a bit.

Sorry to upload such a cliche picture -- another infant sunflower! -- but I just got a new display and wanted to play around and test it out. (See below) I also wanted to post a fresh macro shot for a new group I was invited to join, the wonderful Micro-Nikkor group. This was shot with the 60 macro, no rings, in my side flower bed. (You'll have to view it large to see the single filament.)

I thought the purple leaves were cool, but upon further inspection I found these neat hairs that looked a little bit like strings of diamonds. Even cooler!
