You feed in a long-ish sentence (long ones will either take too long to process or won't work, short sentences are less fun) and it will perform a magic operation (including shuffling up the chinese characters) on the sentence, before regurgitating a cursed version of it. It is very entertaining.
I just added a function that puts the chinese characters in a random order before translation back to english. pssst, the phrase [removed by ST] translates to "n pcs characters" for some reason
