Remember when, back in 1999, someone sent you an email with all the letters jumbled up, and yet you could still understand it? Well, I have written a wee program to automatically jumble up sentences, but abiding to the rule to keep the first and last letter the same. As you will see if you try it out, people who make the claim that the human brain can still scan the sentences without any difficulty, pick their sentences carefully, as most are hard to translate.
Enter some text. The letters in each word will then be jumbled up.
