Placed over the front of the 5" length snoot with straws, the object was to see if I could reduce the size of the outputted light circle. It works and results in the attatched graphic.
Knowing Mark has made rectangular units, this principle would allow moving from rectangular through square to circular light pattern with different shaped cut cards.

Cunning Don! I have a stack of straws, card and tape waiting for me to cut and craft into snoots...looks like I will have to play with a circular adaptor too!
I also noticed that your images nicely demonstrate how the light from the lower flash power falls off faster - the image where you moved the flash closer and halved the power didn't light the background but kept the subject exposure constant.
