Three years ago Old Hat created a post about this fly, but it was before I joined, and the photo is now missing. Here's what's left of that post:

Carl, if you still have that photo, feel free to repost here. I'm really regretting that I don't have photos of REE's version of this fly, which are stunningly perfect and gorgeous, and simple.

Based on Ron's recommendation, I decided to try tying and fishing them.
The hooks are sizes 12 to 16, with probably one-too-many winds of hackle on some.
The dubbing is a mix of merino wool and seal, yellow and orange, mostly on a Clark loop.
Black hen, and a few with dark brown dun hen.
Three of the flies in the bottom row have a little extra loop of flash under the hackle to imitate the bubble.
Ron explained that this fly proves that fish can count, since one loop of flash, or three loops, won't work. The trout will only eat if they count two loops.
My wife and I hooked several trout with these, but only netted one of them. Dry flies seemed to be getting all the action while we were there.
