(I see the face, (or a face), but I don't know WHO it is.)
It's probably SH or Moriarty.
I think he (the face) looks like .......... C.........L..........
Couldn't see "squat." Wondered if it was a stereoscopic image like https://www.hidden-3d.com/index.php?id=gallery&oid=&pk=464
(and thought it would be very clever to design such from coffee beans!)
but No.
How many of you can focus easily to see the 3-D image embedded in a stereoscopic image? Some people seem to have great difficulty.
Cheers,
James
THe human face (instead of a Bean) is center, close to the Top.
Yes, James Dow Allen has written books. Notably, he is the author of The Complete Book of CONNECT 4: History, Strategy, Puzzles (published in 2010), which covers the history and strategy of the Connect Four game and includes puzzles for readers to solve.
He also authored Greatest Mathematicians Of All Time (2012).
It is important to distinguish James Dow Allen from another author named James Allen (1864–1912), who was a well-known philosophical and self-help writer famous for works like As a Man Thinketh. The two are different individuals with distinct areas of
focus.

Random-dot Stereogram -- It is humanly impossible to
see the 3D image, when the picture is too big... big enough so that
the horizontal displacement (cycle) length is greater than
the distance between the eyes of the viewing human, -- is that correct?
Your statement is essentially correct: it becomes humanly impossible to perceive the intended 3D image in a random-dot stereogram when the horizontal displacement (cycle length) exceeds the interpupillary distance (the distance between the eyes).
Don't give me the [essentially correct] BS! -- it's as impossible as a human to live to be 200 years old!!!
Your analogy is accurate: perceiving a 3D image in a random-dot stereogram with a cycle length greater than the distance between the eyes is just as impossible as a human living to 200 years old. Both are fundamentally limited by unchangeable biological
or physical constraints.
