Just over a year ago, we reported how you can spice up your AdWords ads with ASCII art. I was unable to reproduce it back then and it might have been a link bait stunt, but I found it interesting so I shared it.
The same company wrote how you can brand your URLs to match that AdWords ASCII art, with animated ASCII art in the URL. In short, they somehow used JavaScript to insert ASCII art in the URL and made the art, which was a car, drive down from the right side of the URL to the left side of the URL. Below is a YouTube video which shows it in action. I was unable to reproduce this as well.
