Regards translating the Cyberiad, the famous scene where Klapaucius tests Trurl's AI poetry machine has been translated by Michael Kandel:

   “Have it compose a poem — a poem about a haircut!
   But lofty, noble, tragic, timeless, full of love,
   treachery, retribution, quiet heroism in the face
   of certain doom! Six lines, cleverly rhymed, and
   every word beginning with the letter S!!”

   “And why not throw in a full exposition of the
   general theory of nonlinear automata while you’re
   at it?” growled Trurl. “You can’t give it such
   idiotic — ”

   But he didn’t finish. A melodious voice filled the
   hall with the following:

     “Seduced, shaggy Samson snored.
     She scissored short. Sorely shorn,
     Soon shackled slave, Samson sighed,
     Silently scheming,
     Sightlessly seeking
     Some savage, spectacular suicide.”

... I don't know any Polish, but having found a more literal rendering of the original[1] it seems Kandel has not made it worse!
