Messages were encoded according to the following steps:

1.) For all letters, convert to a number according to the alphabetic position (A -> 1, B -> 2, etc.)

2.) Subtract 12 from each number

3.) If a resulting number is less than or equal to zero, subtract one more (this gets rid of any zeros)

4.) Convert all positive numbers to their alphabetic equivalent (1 -> A, 2 -> B, etc.)

5.) For all negative numbers, take the absolute value and convert that to their alphabetic equivalent. Follow the letter with a (pseudo

^{*})random integer.Thus, the encoded message HH8L9, H1L9FA9 F4FH8M, E1CH can be decoded as follows:

H -> 8, 8+12 = 20 -> T

H8 -> -8, -8+13 = 5 -> E

L9 -> -12, -12+13 = 1 -> A

and so on, to reveal the original message TEA, EARL GREY, HOT

Since I had decided to make the category classic science fiction film and television, I went with the two messages that are most iconic in my mind of the genre:

Message 1

SPACE: THE FINAL FRONTIER. THESE ARE THE VOYAGES OF THE STARSHIP ENTERPRISE. ITS FIVE-YEAR MISSION: TO EXPLORE STRANGE NEW WORLDS, TO SEEK OUT NEW LIFE AND NEW CIVILIZATIONS, TO BOLDLY GO WHERE NO MAN HAS GONE BEFORE.

Message 2

A LONG TIME AGO IN A GALAXY FAR, FAR AWAY... STAR WARS
