Infocom's classic interactive fiction version of The Hitchhiker's Guide to the Galaxy came with a fantastic assortment of feelies -- cool little trinkets and papers to encourage people to buy the game instead of just making a copy of their friend's.
Among them were an "order for destruction" of Arthur Dent's house and a similar-looking form that appeared to be an order for the destruction of Earth. However, it was written in an alien alphabet (which looks like a cross between Greek and Cyrillic), so there was no way to be certain.
I decided to take another look at it recently, to see if it was written in some kind of code. It turns out that it's just a simple cryptogram! I figured someone out there on the Internet must have deciphered this by now and posted it somewhere, but I can't actually find any other page about it on Google, so I guess this is the Internet debut. Drumroll please...
(BTW, all typos are reproduced verbatim. A few "uppercase" alien letters were undecipherable; those are represented with question marks.)
There's also a few barcodes, though only one of them seems to parse. It evaluates to 051051010289, which seems to be a UPC symbol for a nonexistent product, though with a manufacturer ID belonging to Infocom.
