Randomly, I made a letter flipper thingy the other day. I saw a similiarish effect on a Flash site and tried doing it with JavaScript instead. You can view source on that page to see the simple code. It's just recursively calling a function to change the letter with a slight delay until the letters stored in a Array are up, then changing back to it's original letter.

Then Don Burks turned it into a plugin which is far more robust.

Nope, it's not the most useful thing in the world. I just thought I'd share it in case anyone gets a kick out of it or it actually comes in useful somehow.
