I like your point, and I like the way you were polite about it.

ive not seen split tupperware thingies.  only one direction. while i have my concerns as to how much light actually gets pushed out of each side after accounting for mirror/prism and other losses it does appear to be unique in the floor/ceiling or two sided approach.

EDIT: found this on their website. with all the random catchlights in the eyes, it appears to be a diabolical way to confuse those (how did they do this?) threads

for close up flower (or bug) photographer a used vivitar ringlight would be a better investment.  they go for under 60$ on eBay all the time.  They were designed for close up work.  dentists used to use them then suddenly the market was flooded with used ones so someone must have designed something that dentists 'had' to have.

much better than any diffuser setup
