Oh great, I did this

--8<---------------cut here---------------start------------->8---
(defun growl-popup (msg)
  "Show a popup using growl notification or say it, only working on OSX with 
growlnotify in the $PATH"
  (interactive)
  (if window-system
      (shell-command (concat "growlnotify -a /Applications/Emacs.app/ -m " msg))
    (message msg)))

(defun popup-last ()
  (interactive)
  (growl-popup (format "%s" last-command)))

(add-hook 'post-command-hook 'popup-last)
--8<---------------cut here---------------end--------------->8---

And now emacs is going crazy, when I try to evaluate something it tries
to execute it in the shell.

I then removed the hook with
(setq post-command-hook (remq 'popup-last post-command-hook))

but it didn't listen, it's continuing to use it indefinitely...

Other problems are:
- the command is shown after (not during)
- I should remove useless stuff like self-insert-command
- I want to see the keyboard combination, not the full name of the
command...
