I found out this optical illusion has a name -blivet -
In its most common usage, the word "blivet" refers to an indecipherable figure, illustrated above. It appeared on the March 1965 cover of Mad magazine bearing the caption "Introducing 'The Mad Poiuyt' " (the last six letters on the top row of many Latin-script typewriter keyboards, right to left), and has appeared numerous times since then. An anonymously-contributed version described as a "hole location gauge" was printed in the June 1964 issue of Analog Science Fiction and Fact, with the comment that "this outrageous piece of draftsmanship evidently escaped from the Finagle & Diddle Engineering Works" (although something else called a "hole location gauge" had already been patented in 1961[2]).The graphic artist M. C. Escher used these types of figures as the basis for impossible three-dimensional compositions in many of his woodcut prints.

In December 1968 American optical designer and artist Roger Hayward wrote "Blivets: Research and Development" for The Worm Runner's Digest in which he presented interpretations of the blivet.



I was using the more conventional military term, "blivet", though, when I was referring to a builder's 383 built Chevy motor in a bugeye Sprite -- "10 pounds of sh-- in a 5 pound bag.

 
Interesting background Rick; thanks for the researching it.
 
Hmmmm.... I always heard another definition of blivet....

Yeah - me too. "Blivet is a python module for management of a system's storage configuration. It is used by Anaconda, Fedora's OS installer and used to exist as pyanaconda.storage."

Just want to clarify things ...
 
Still not the one....

Matches Rick's final comment.
