[Emanuel Berg <moasenwood@zoho.eu>]

Here [1] is a little something that can be
interesting, who knows?

(defun scramble (beg end)
  "Shuffle chars in region from BEG to END."
  (interactive "r")
  (when (use-region-p)
    (save-excursion
      (let*((str        (region-to-string))
            (chars      (delete "" (split-string str "")))
            (rand-chars (sort chars (lambda (a b) (zerop (random 2))))) )
        (delete-region beg end)
        (dolist (c rand-chars)
          (insert c) )))))
