It comes in a variety of colours and is designed to appeal to young people with its hip-hop or graffitti style. The numbers form an outline vaguely similar to the map of Greater London but it is also intended to be used extensively in moving form, where the changing colours and patterns make it a little less strange. That did not stop controversy over the design which appears to have not that many fans.

Unfortunately, one section of the video promotion featuring it has had to be pulled after it induced epileptic fits in some people.
