This USB LED Message Fan uses the ol’ persistence of vision thing to get your message across and broadcast a 16 character message to the office. It’s also a fan, so it’ll keep you cool. Or something. All you need is 8 more and you can hack them to display your tweets. Or not. US$16.

Hard to say the words? Make them appear in the air. Customize your messages like “I Love U”, “Sorry!”. Just turn it on, then your message will be created in the air by a strip of red LED. 16 characters can be stored and shown.
