how to make a counter like badoo.com
<p>I'm really amazed with Badoo.com counter.
How can we implement such a graphical counter, wich is by the way very eye-catching.
When It adds one number it shows all the number from 0 to that number. 
With firebug I just noticed that all of it a picture.
They use css to show a specific number.<br>
thanks  </p>
