Converting to Secret Language Write some code in any language that inputs a string such as "Today is a great day" (Note that there is no punctuation) and converts it to the "Secret Language". Here are the rules for the "Secret Language".


a=c, b=d, c=e and so on (y=a and z=b)
separate each word by a space
make sure there is proper capitalization


Example:

Input: "Today is a great day"

Output: "Vqfca ku c itgcv fca"


It is a popularity-contest. Other users should give points by looking for most "to the point" yet "unique" code.

CHALLENGE:
I was looking up uncommon programming languages and I found a language called Piet (esolang). I challenge anyone to write it in this language.

I am lucky - it is already in the String class:
'Today is a great day' rot:2
    -&gt; 'Vqfca ku c itgcv fca'

adding I/O, this makes it:
(Stdin nextLine rot:2)print

in the spirit of doorknob's obfuscated example below, how about:
Parser evaluate:('(Uvfkp pgzvNkpg tqv:2)rtkpvPN' rot:-2)
