I’m almost afraid to ask after the other poster got their head bitten off, but what is a grue? :)
Grrrr ... SNAP GROWL BARK OBAMA! :-P
A grue was an evil monster in a very old computer game series called “Zork”. This was back before adventure games had graphics. They were all text based (i.e. you’d read the story ... again, absolutely no graphics ... not even ASCII based graphics). The user would enter basic commands like “go north”, “get sword”, etc. to move through the world :-)!
They were great stories with some cool puzzles. I loved those games growing up. I am a computer engineer by trade ... learning how those games worked taught me a lot about computer programming (arrays, garbage collection, etc).
