The variable frame-title-format can be customized to show various stuffs. Today, I will give a short tutorial to let Emacs frame show random quotes each time emacs is launched.

1. Let's define a list called quotes which stores the quotes at first. I just grabbed those quotes from an emacs package thisirs/scratch-message.

2. Next we should take one quote each time to display it. The variable can be customized as followed:

   (setq frame-title-format
      (nth (random (length quotes)) quotes))

Paste the above code into your init file, and you will see the effect next time you launch your emacs. Any improvement and advice are appreciated.
