OZY: the Xtal Logo!
The originator of the "OZY" header, as it was known, was the XRAY and XTAL laird and founding father Jim Stewart. Jim had a realistic view of the longevity of computers and software, and he thought that Shelley's poem "Ozymandius" reflected the fragility of massive programming efforts, especially in the 60's and 70's. The OZY header became the signature of software that Jim and others helped develop. Even today, it still seems rather apt.
Here is Shelley's poem "OZYMANDIUS, King of Kings":
I met a traveller from an antique land who said... Two vast and trunkless legs of stone stand in the desert, near them, on the sand, half sunk, a shattered visage lies, whose frown, and wrinkled lip, and sneer of cold command tell that its sculptor well those passions read which yet survive, stamped on these lifeless things the hand that mocked them, and the heart that fed - and on the pedestal these words appear.... MY NAME IS OZYMANDIAS KING OF KINGS LOOK ON MY WORKS YE MIGHTY AND DESPAIR. Nothing beside remains, round the decay of that colossal wreck, boundless and bare the lone and level sands stretch far away.
