Thanks Piergiorgio. I think I saw this some years ago. This is a real
mind job! I could see it both ways, initially counter.

Why odd?
You know this:
https://en.wikipedia.org/wiki/Spinning_Dancer
Well, it is possible, with some focusing, to change
the spinning direction.
Like the acustic illusion, this one has two possible
interpretation, which can be switched, with some
effort indeed.

A change with the same listener on the same equipment is very
odd indeed!

A recent New York Times article discusses this. May be helpful:
<https://www.nytimes.com/interactive/2018/05/16/upshot/audio-clip-yanny-laurel-debate.html>
The internet erupted in disagreement on Tuesday over an audio clip in
which the name being said depends on the listener. Some hear “Laurel.”
Others hear “Yanny.”
We built a tool to gradually accentuate different frequencies in the
original audio clip. Which word or name do you hear, and how far do you
have to move the slider to hear the other? (The slider’s center point
represents the original recording.)
The clip and original “Yanny or Laurel” poll were posted on Instagram,
Reddit and other sites by high school students who said that it had been
recorded from a vocabulary website playing through the speakers on a
computer.
One detail may frustrate some and vindicate others: The original clip
came from the vocabulary.com page for “laurel,” the word for a wreath
worn on the head, “usually a symbol of victory.”
One way to understand the dynamics at work is to look at a type of
chart called a spectrogram — a way to visualize how the strength of
different sound frequencies varies over time. The spectrograms above
show that the word “laurel” is strongest in lower frequencies, while a
simulated version of the word “yanny” is stronger in higher frequencies.
The audio clip shows a mixture of both.
By using the slider to manipulate which frequencies are emphasized, it
makes one word or the other more prominent.

I can hear either just by thinking of the word before it is played. What witchery is this I doth ask.

I heard Yanni the very first instance the first time I heard it played
repetitively, but Laurel ever since then. Very interesting.

It seems to me there are several links to different
level of explanations.
In any case, what is your idea of "well-explained",
when we talk about *optical* illusions?

Well, Wikipedia editors can't do their own analysis so they are
limited in that sense.
Were someone to publish a better analysis, then that could be
included in the Wiki page.
It is ripe for more analysis, and possibly even applications.
(Some sort of "code-talking" comes to mind.)
