The blivet is an undecipherable figure, an optical illusion and an impossible object. It appears to have three cylindrical prongs at one end which then mysteriously transform into two rectangular prongs at the other end.
Blivet has numerous other meanings, explained below.
Paradoxical graphic figureEdit
In yet another usage, illustrated above, the blivet is an undecipherable figure. It appeared on the March 1965 cover of Mad magazine, where it was dubbed the poiuyt (derived from the last 6 letters on the top row of the typewriter keyboard, 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".
The artist M.C. Escher was famous for utilizing this object in many of his drawings, lithographs, woodcuts and many such other media.
