Interesting Uses For a USB LED Screen?

Hogwash McFly writes "My boss gave me one of those USB-powered red LED scrolling displays as a Christmas gift, and while cycling the usual 'I read your emails' and 'ID10T Error' messages will be entertaining for a day or two, I was wondering if it could be put to more constructive uses. The configuration file is plaintext and supports different scroll speeds, flashing, bitmaps, and WAV sounds. The font is defined as 5x5 pixels per character, also stored in plaintext as 5 hex values, one for each vertical line of pixels. A dynamically generated message could prove useful in my day-to-day work on the helpdesk, but are there any interesting uses beyond network notifications and news feeds?"

    OK! Useful. Here's what you do...

    The day before you leave on your next vacation, set it up so that it loops the message "I love you!" and then set up the .wav file of Barney the dinosaur singing his "I love you, you love me" theme song. Remove the socket covers from your cube wall and attach the electrical leads that power the device directly to the power lines, covering them with two-inch thick conduit. Then epoxy encapsulate that power connection really well (if the connection happens to be through a wall wart, be sure to conduit and encapsulate those connections as well). Disable any power switch the device might have and leave. When you get back from your vacation, your co-workers will have all either quit or committed suicide and your path to the next level up the corporate chain will be cleared. Repeat as necessary until you are CEO. Take golden parachute and leave. You win!
