This sounds like the title of a Chuck Norris movie - he plays Ansel Adams in a blockbuster where he defeats the evil power of something. The idea of Ansel Adams stripped to the waist firing a machine gun is oddly appealing*.
Coming away from that, I discovered that we have an all-in-one kit for active hobbyists who have at least one speed light and the desire to modify the output. You get attachment accessories that let you put on a snoot, diffuser, grids, filters, or small softbox. The filter holder bears a slight resemblance to the ones made by C---n or L-- but is sized for 3 1/2 inch filters and good luck finding those.
The rest of the gear is pretty useful, and as it is all in one set you can get a good variety of looks going and experiment. If you've got a speed light setup that runs to several heads it is perfect for portable portraiture.
Pardon the terrible pack shots but it is too big to fit in the editorial light tent.
* They cancelled the planned movie about my life when Don Knotts died and they couldn't find anyone else to play me. I tried out for the part but they said I was too derivative.
